Course Overview

This syllabus outlines the structure, policies, and expectations for Math 20C: Multivariable Calculus at UC San Diego. The course covers key topics in vector geometry, vector-valued functions, partial differentiation, optimization, and double integration, providing a foundation for advanced study in calculus and related fields.

Course Content and Topics

• Vector Geometry: Introduction to vectors in two and three dimensions, operations, and geometric interpretations.

• Vector-Valued Functions and Their Derivatives: Study of functions whose outputs are vectors, including differentiation and applications to motion in space.

• Partial Differentiation: Techniques for differentiating functions of several variables, including higher-order partial derivatives.

• Maxima and Minima: Methods for finding local and global extrema of multivariable functions, including the use of the second derivative test and Lagrange multipliers.

• Double Integration: Evaluation of integrals over two-dimensional regions, including applications to area and volume.

Additional info: The course calendar references textbook sections 12.1–15.2, which typically correspond to chapters on vectors, vector-valued functions, partial derivatives, multiple integrals, and applications in standard calculus textbooks.

Prerequisites

• AP Calculus BC score of 4 or 5, or completion of MATH 20B with a grade of C– or better.

Textbook

• Calculus Early Transcendentals: Multivariable with Achieve, Rogawski, 4th edition.

Course Structure and Grading

• Homework: Two types—graded online assignments (via Achieve) and ungraded textbook problems. The lowest three online homework scores are dropped.

• Exams: Two midterms (best score counted) and one comprehensive final exam. No make-up exams except in extreme cases.

• Grading Scheme:

  • Homework: 20%

  • Best Midterm: 35%

  • Final Exam: 45%

Course Calendar (Topics by Week)

Additional info: Section numbers (12.1–15.2) correspond to standard multivariable calculus topics such as vectors, vector-valued functions, partial derivatives, multiple integrals, and their applications.

Course Policies and Academic Integrity

• Homework Collaboration: Discussion is allowed, but final write-up must be individual work.

• Academic Integrity: Strict adherence to UCSD's policy; violations include plagiarism, unauthorized collaboration, and use of prohibited aids.

• Makeup Policy: Makeups are rarely granted and only in extreme, documented circumstances.

• Regrades: Requests must be made within a short window after grades are posted on Gradescope.

• Equity and Inclusion: The course adheres to UCSD's Principles of Community, supporting diversity and respect.

Study Suggestions

• Allocate sufficient weekly study time (about 12 hours outside lecture for a 4-unit course).

• Start homework early and read textbook sections before lectures.

• Take notes by hand for better retention.

• Attempt problems before consulting solutions.

• Use mistakes as learning opportunities.

• Teach concepts to others to reinforce understanding.

• Application: Describes motion in space, where gives the position of a particle at time .

Partial Derivatives

• Partial Derivative: The derivative of a multivariable function with respect to one variable, holding others constant.

• Notation: , , etc.

• Example: For , and .

Double Integrals

• Double Integral: Used to compute the volume under a surface over a region in the -plane.

• Notation:

• Example: over a circular region .

Optimization (Maxima and Minima)

• Critical Point: A point where all first partial derivatives are zero or undefined.

• Second Derivative Test: Used to classify critical points as local maxima, minima, or saddle points.

• Lagrange Multipliers: Technique for constrained optimization.
