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%) Homework assignment is the most important part of this course. Homework will be assigned during the semester. There are two kinds of assignments. The first is basic skills. You do these problems on Mymathlab (you will receive the course ID in email); the second is more advanced problems. These assignments will be posted on the course webpage. You do these problems on paper, write the solutions following basic mathematics writing standards (to be introduced), and hand in for grading. After an assignment has been turned in, the solution to the problems will be posted on the course webpage. Late homework (after the solution has been posted) will not be accepted. The lowest homework assignment score will be dropped when calculating the final course grade.

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 Monday, May 6, 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.
