Lecture time MWF 9:30-10:20 am, ED 401

Textbook Calculus, by Briggs and Cochran, 11th complete edition (You may use “volume 2: multivariable” instead of the complete edition. The only difference is the chapter labeling: Chapter 12 in the complete edition corresponds to Chapter 11 in “volume 2: multivariable”, and so forth.)

Homework (30%) There will be 10 homework assignments. They will be assigned during the semester on weekly basis, and due at the beginning of Monday's class as specified on the tentative schedule below. Each student will be given three days of free extension. You can use all the three days in one assignment, or use them in two or three assignments. After you have consumed your three free extension days, you can still ask for extension, but for each additional extension day, I will subtract 10% of that assignment.

Midterm Exams (15% X 3) Three midterm examinations are scheduled on the days specified on the tentative schedule. A make-up examination is possible only if you get my permission before the examination, or with a doctor’s note.

Final Exam (25%) Final examination is scheduled on Wednesday, May 14, 10:00 am—12:00 pm.

Grading Course grades are determined by: A (90.0%-100%); B (80.0%-89.9%); C (70.0%-79.9%); D (60.0%-69.9%); F (<60.0%).

Short Summary This course covers multivariable calculus using a highly geometric approach. We first give a treatment of three-dimensional geometry; introduce vectors, dot product, cross product, lines, planes, and how to visualize a surface in three-dimensional space using contour maps and level curves. Then, we cover vector-valued functions (parametric curves), and their derivatives, integrals, curve length, curvature. Next, we extend single variable calculus to multivariable; cover functions of several variables, and their limits and partial derivatives, gradients, directional derivatives, local and absolute maximum/minimum, and Lagrange Multipliers. We then cover two- and three-dimensional integrals in rectangular, polar, cylindrical, and sphere coordinates, and changing variables. Finally, we cover line integrals in two- and three-dimensional spaces, and put the capstone of the course: the Fundamental Theorem of Line Integrals which relates gradients with integrals, and Green’s Theorem which relates line integrals with double integrals. If time permits, we also briefly introduce curl and divergence, surface integrals, Stokes’ Theorem and Gauss’ Theorem.
