Welcome

Whether prompted by the necessity for survival, or, as we would prefer, motivated by curiosity and a search for meaning, humanity has sought to make sense of nature and to create models of natural phenomena amenable to our minds. Thus our contribution to nature is in enabling its introspection. The conception of predictive models of natural phenomena is the subject of natural science. The applications of their predictive powers are the matter of technology and medicine. The world in which these models actually exist, however, is the realm of mathematics. To quote one of the giants of this scientific adventure:

A Quote of Galileo

“Philosophy is written in this grand book, the universe, which stands continually open to our gaze. But the book cannot be understood unless one first learns to comprehend the language and read the letters in which it is composed. It is written in the language of mathematics, and its characters are triangles, circles and other geometric figures without which it is humanly impossible to understand a single word of it; without these, one wanders about in a dark labyrinth.”

—Galileo, Il Saggiatore (1623), translated by Stillman Drake (1957)

The search for a proper description of these geometric figures and their motion culminated in the development of calculus in the seventeenth century CE, attributed independently to Isaac Newton (1642–1727) and Gottfried Wilhelm Leibniz (1646–1716), and building on millennia of expansive and deep mathematical research. It took more than an additional century for mathematicians to formalize it and obtain a clear vision and understanding of its concepts and ideas. In fact, the modern formalization of mathematics itself—a very important move toward Platonic pure forms—was a direct descendant of calculus, born from the many challenges posed by its brilliantly intuitive, yet originally unfinished, foundation.

Historically, the early pioneers of calculus operated on intuition, treating certain quantities as “infinitesimally small” without a rigorous way to define what that actually meant, leading to various paradoxes and difficulties. It took over a century of rigorous mathematical refinement to establish the solid logical foundation we use today. The core concept of calculus is the notion of limit, formalized properly in the nineteenth century by mathematicians such as Augustin-Louis Cauchy (1789–1857), Bernard Bolzano (1781–1848), and Karl Weierstrass (1815–1897), among many. Calculus is now a part of the field of analysis, which is by far the most applied area of mathematics to the natural sciences, directly or through some of its descendants, such as probability, statistics, differential geometry, and numerical analysis.

This is the subject to which this course offers an introduction. Our focus will be on the fundamental concepts of limits, continuity, derivatives, and their applications. While we must admit certain foundational results, which are the topics of more advanced courses such as an introduction to real analysis, we will still undertake a deep journey into the subject, intended to convey a sense of its elegance and depth while cultivating the skills necessary to move forward with the study of both mathematics and its applications.

1. Class Philosophy

The narrative of mathematics is written in theorems and proofs.

 

Mathematics tells a story of ideas, where the narrative is driven by logical connections between abstract patterns. It enables us to describe and employ abstract ideas by following precisely where deduction can lead us. The practitioner of mathematics uses their intuition and understanding in a creative manner to discover new theorems about new concepts. Truth in mathematics is established via formal proofs, which use deduction like a physicist exploits causality. A formal proof is a sort of harmony of ideas, where somehow other theorems and concepts come together in a strongly coherent argument. Where a biologist or a physicist uses an experiment as a tool to validate or disprove a hypothesis, mathematicians use formal proofs to confirm whether their theorems are true or not. 

Mathematics may also be seen as an abstract music of the mind. Like music, it has its own language to record the creation of a musician to be shared with other musicians. Yet, the written language of music communicates what is needed to produce the same harmonies, timbres, pitches in the expected sequence and rhythm, playing music involves a lot more than reading the sheet music. The sound produced by a talented musician transcends the written score. In mathematics, we also use a very formal language to communicate our ideas and display our proofs to other mathematicians. In particular for proofs, the language is strict, to ensure correctness. Nonetheless, as with music, it is the collection of ideas, patterns, connections, logical relations, and the entire landscape of mathematics which is the true content of our field. Notation comes alive and meaningful through interpretation and practice.

Watching a talented musician play a beautiful piece does not make one a musician. The same applies to mathematics. Learning mathematics is a very active process which requires trying, experimenting, repeating, and challenging one's work, until understanding emerges. You must train your mind as the instrument of mathematics, and to create your own music, for instance solving a question, you will be led by your comprehension of the ideas, and you will express them carefully in the common language of the field. In particular, proofs are not a secondary component of this exploration and creative process: they are at its core. This sought after understanding emerges from learning the connections and the pictures drawn by the proofs, which are precisely where all these connections appear.

This overall perspective drives our teaching method. We present the subject as a narrative written in definitions, theorems and their proofs. While we may, at times, need to accept a theorem as fact, delaying its proof to a later course, our purpose is to select a collection of proofs which illustrate the core concepts of the present course. The story emerges by revealing connections between the actors. To accommodate the need for feedback and clarification, our course relies heavily on lectures where the audience is strongly encouraged to ask questions. As a mathematician, it is my role to provide a correct argument, illustrate with a proper example, or a counter example, a particular concept, and to be able to answer your questions, offering alternative paths when possible. Indeed, as students, you are not here to merely receive a dogmatic set of disconnected facts, but instead, you are here to be taught a coherent body of knowledge you can navigate logically based upon well stated assumptions. A theorem is true because we prove it so, not because we believe so, or we are told so. In fact, this very mindset is at the core of what I hope to help you learn.

We do not reject incorrect statements or proofs based upon an authoritative view, but by providing counterexamples, in the hope to correct an incorrect intuition. We learn that only proven claims, either in the process of solving a problem or by appealing to results seen in lectures, are admissible and considered true. In this course, points toward the final score are earned only for correct mathematical statements which contribute, or could reasonably contribute, to a correct solution of the problem. 

Students will thus develop their skills by focusing on understanding the material. We expect that definitions and theorems will be learned from one lecture to the next with the necessary rigor. In a calculus course, proofs are to be read and understood, but will not be included in the final assessment, which will instead focus on certain examples and applications. Once the student knows the definitions and theorems, they can attempt to reproduce examples seen in class. They should try to do so by themselves, without recourse to their notes, for a long time. Only after a very diligent effort has been made and failed, should the notes be consulted again. The student should try again later to reproduce the example, after enough time has elapsed since the last consultation of notes that short term memory is no longer of help. This process is akin to repeating musical exercises until they become natural and some of their more subtle aspects become apparent. At this point, the student can then attempt the exercises. Again, sometimes, maybe often, exercises may raise a challenge or a question: this is a positive development. Learning, in particular, relies on first encountering friction, difficulties, which in turn require the mind to work and relate acquired knowledge through creative yet logical skills to build a new solution. 

The entire reason that a mathematician teaches this course is that, for the time of the lecture at least, you have direct access to someone who has demonstrated some abilities in the field. It is thus very important that you take advantage of this opportunity. You must carefully listen to what is said, take excellent notes for later review, and ask questions at the first confusion. In exchange for your efforts, you will progress on your journey in discovering the world of mathematics and its myriad of applications.

2. Prerequisites

The official prerequisite is MATH 1070 or an equivalent course. Students should enter with solid proficiency in precalculus, including basic algebraic manipulation, factorization of quadratic polynomials, basic trigonometry and the principal identities for sine and cosine, and basic properties of exponential and logarithmic functions. Students who have not yet mastered these topics should consult the instructor or their academic adviser promptly about appropriate preparation.

To do well in this course, you will also need intellectual curiosity, a serious interest in the subject, a strong work ethic, and a willingness to be challenged. This course is designed for students who want to gain a conceptual understanding of calculus from which practical skills can emerge.

3. Catalogue Description

The University of Denver catalogue gives the following description:

Limits, continuity, differentiation of functions of one variable, applications of the derivative. This course counts toward the Analytical Inquiry: The Natural and Physical World requirement. Prerequisite: MATH 1070 or equivalent.

4. Learning Outcomes

By the end of the course, a successful student should be able to:

The November 2 deadline is taken from the University of Denver’s 2026–2027 Registration and Billing Dates for Traditional Programs. Students remain responsible for consulting the Registrar for the procedure and any consequences associated with dropping a course.

7. Resources

Many excellent resources for calculus are available online, and you are welcome to use them for study. The department has also adopted the open-source calculus textbook published by OpenStax. This course is designed primarily around the lectures, during which all material required for the course will be presented. Canvas will contain announcements and essential course materials.

Two sets of instructor notes are provided as supplementary resources:

Calculus I Instructor Notes. These notes present the theoretical content of the course, including most proofs discussed in class as well as some additional results. Examples, exercises, and mathematical discussions will principally take place during lectures. The notes serve both as a reference and as a more detailed complement to the lectures.

Foundations of Calculus Distilled Notes. These short notes contain a synopsis of the foundation of calculus notes, with the primary pictures and formulas for quick access. These can serve as a quick reference guide.

Foundations of Calculus Instructor Notes. These (supplemental) notes describe the mathematical foundation upon which the course is built. In particular, they state our formal framework using nine fundamental axioms concerning sets, functions, and real numbers. They also review elements of plane geometry and trigonometry, together with other important families of functions, including quadratic, exponential, and logarithmic functions. These notes can be used as a reference and could serve for a as-of-yet non-existence serious precalculus course; they contain much more material than our class will need but offer an appropriate foundation for calculus. Students can consult them as a references by accessing only what they need, and may browse them to see how the story of calculus is rooted in a formal theory of sets, functions and real numbers.

8. Course Format and Expectations

This course relies on active engagement to master mathematical concepts.

Lectures and participation. Regular attendance and diligent note-taking are expected. Lectures are interactive, and you are encouraged to seek clarification whenever a concept is unclear.

Homework. Assignments are provided for practice rather than assessment. Homework is not collected or graded, but consistent completion is essential for success.

Tuesday problem-solving. A portion of Tuesday’s meeting will be reserved, when appropriate, for questions arising from the week’s work and for additional practice.

Friday TA session. The Teaching Assistant will lead a weekly practice session on Fridays from 12:00 to 12:50 p.m. in Olin 205.

Exam preparation. You should be able to reconstruct the examples developed in lecture independently. Use lectures, office hours, and the Friday TA session to identify and resolve specific conceptual or technical difficulties.

Canvas. Course announcements, schedule changes, and essential materials will be posted on Canvas. Students are responsible for checking Canvas regularly.

9. Assessment and Grading

The course grade is based entirely on in-class examinations. The grading rule is designed to preserve the importance of the midterm while providing a meaningful opportunity to demonstrate improvement.

Assessment Components

Midterm examination. A mandatory assessment covering approximately the first half of the course, administered Thursday, October 22.

Optional makeup midterm. A second assessment of the same material, administered Thursday, October 29. A student may take it after taking the original midterm, or after missing the original midterm for a documented reason accepted under the missed-examination policy below. When both examinations are taken, only the higher score is used.

Final examination. A comprehensive examination administered Friday, November 20, from 12:00 to 1:50 p.m. in Olin 205.

Examination Conditions

All examinations are closed-note and closed-book. Only examination paper supplied by the instructor, pens or pencils, and erasers are permitted. Calculators, phones, computers, smart watches, books, notes, and other aids are prohibited unless specifically authorized as an approved accommodation. Students may not communicate with one another or view another student’s work during the examination and must observe the proctor’s announced start and end times.

Final Score Calculation

Let M denote the mid-quarter score:

Let F denote the final-examination score, and let S denote the final course score.

Grade computation formula

S = ½(F + M) + ¼ max{F − M, 0}

Equivalently: S = max{(F + M)/2, (3F + M)/4}.

This policy rewards improvement on the final examination while ensuring that the midterm remains an important part of the course.

Grading Scale

Score to Letter grade correspondence
Course score S Letter grade Course score S Letter grade
[85, 100] A [67, 70) C+
[80, 85) A− [63, 67) C
[77, 80) B+ [60, 63) C−
[73, 77) B [57, 60) D+
[70, 73) B− [53, 57) D
[50, 53) D−
[0, 50) F

Missed Examinations and the Optional Makeup

Optional status. The makeup midterm is optional. Because M is the maximum of the two midterm scores when both are taken, taking the makeup cannot lower M.

Eligibility. A student is eligible to take the optional makeup after taking the original midterm, or after missing the original midterm for an accepted documented reason. Students who miss the original midterm should contact the instructor as soon as reasonably possible and ordinarily before the makeup date. Documentation should be submitted through the appropriate University process whenever one exists; students should not send private medical details directly to the instructor.

Accepted absences. University-approved disability or religious accommodations, official University activities, and documented emergencies or serious illness will be handled in accordance with University policy. Other circumstances will be considered under the applicable University procedures.

No additional makeup. Except where an approved accommodation or University policy requires otherwise, no alternate date or additional makeup will be offered for the optional makeup midterm.

Missing both midterms. If M = 0, then S cannot exceed 75; therefore, the highest possible course grade is B.

Missing the final. If F = 0, then S cannot exceed 50; therefore, the highest possible course grade is D−.

Academic Integrity During Examinations

The use of an unauthorized aid, unauthorized communication, viewing another student’s work, or permitting another student to view one’s work is prohibited. Suspected violations will be addressed under the University of Denver Honor Code and applicable academic-integrity procedures. A violation established through the applicable process will result in a grade of F on the examination and may have additional consequences under University policy.

10. Attendance, Absences, and Course Continuity

Attendance and participation are important for mastery of the course material. Students are expected to attend regularly and remain responsible for material and announcements from any class they miss. Attendance itself is not included in the numerical course grade.

Students with an approved Adjusted Attendance accommodation should contact the instructor to discuss how the accommodation will operate in relation to the learning goals and examinations of this course. Students anticipating absences for religious observances, official University activities, or other approved reasons should follow the relevant University procedure and communicate as early as possible.

If campus closure or an unexpected instructor absence requires a change in delivery, instructions will be communicated through Canvas. Students should familiarize themselves with the Canvas course at the beginning of the term.

11. About Your Instructor

I am a tenured, full professor of Mathematics at the University of Denver. I have a Ph.D. in mathematics from the University of California, Berkeley, as well as a Masters degree in Statistics from U.C. Berkeley, a degree of Statisticien-Economiste / Ingenieur Statisticien (Master equivalent) from ENSAE Paris (Ecole Nationale de Statististique et de l'Aministration Economique), a member Grande Ecole of the ParisTech institute, and a Maitrise de Mathematique et Applications Fondamentales from the University of Pierre et Marie Curie, Paris 6.

My research specialty is noncommutative metric geometry, a field at the intersection of metric geometry, differential geometry, quantum geometry, quantum algebras, functional analysis and mathematical physics. My principal contribution is the discovery and study of distances between quantum metric spaces, motivated by the Gromov-Hausdorff distance. Thus I am a functional analyst, which is a far reaching discipline of mathematics whose roots lay in calculus. I currently have more than fifty papers published in peer reviewed international journals in mathematics, all publically accessible on the ArXiv preprint site. Mathematics is my passion.

My teaching is heavily influenced by my international education and my passion and knowledge of mathematics. As a researcher in analysis, I have gained a deep understanding of the subject, which I now enriched with my own discoveries, and I have developed a perspective on the field and a particular intuition about its concepts and ideas. My purpose is to present the material with rigor, context, and with respect for the intelligence of my students. I love to present mathematics while preserving its elegance, as I know that what matters most in teaching mathematics is to awake students to the incredible world of ideas of mathematics, as a form of music for the mind.
