Midterm I Wed October 1 4.00 pm - 5.20 pm Library E4320

The first midterm exam will cover the materials of Chapters 1, 2 and 4 in the textbook with the exclusion of: section 6 in Chapter 1; section 1B in Chapter 2; sections 1E, 2C, 4C in Chapter 4.

There will be three problems in the exam.

One is about lines, planes and vectors: parametric representations and equations of lines and planes; calculation of projections, distances and angles using the dot product.

A second problem is about systems of linear equations: study the set of solutions using row operations, determinants, inverses, etc.

A final problem is about parametrized curves and surfaces: curves on surfaces, partial derivatives, tangent lines and tangent planes, length of curves, etc.

Some suggestions to prepare for the exam are: review your notes, the textbook and the homework assignments. Work through the examples in the textbook and your notes on your own, make sure you understand homework corrections. Most important of all, do plenty of exercises (there are extra exercises at the end of every chapter in the textbook).

Midterm II Wed November 12 4.00 pm - 5.20 pm Library E4320

The exam will cover Chapters 5, 6 and 7 and section 8.1. A more detailed description of what will be in the exam and what sections in each chapter you can skip is given below. I have also indicated exercises in the textbook which might be useful. Of course you are not required to do all of them, but it is a good idea to solve as many as possible. In order to prepare well for the exam, you should also review the textbook, your notes and past homework assignments. You are encouraged to meet me or Shalin during office hours next week for any doubt and to come to the lecture and recitation on Monday Nov 10 ready to ask plenty of questions.

Final Exam Tue December 9 8.30 pm - 11.00 pm Library E4320

The final exam is cumulative, covering everything we have studied during the semester. However, extra emphasis will be given to Chapters 8 and 9.

See the info about midterm exams for what you can skip in Chapters 1, 2, 3, 5, 6 and 7, with one change: section 6 in Chapter 1 (the cross product) is a prerequisite for some of the material in Chapter 9, so you should be familiar with it.

Chapter 8.

Definition of line integrals. Fundamental Theorem of Calculus and its consequences. Arc-length parametrization. Curvature. Divergence and curl of a vector field.

Chapter 9.

Green’s theorem. Path independence principle. Gauss’s and Stokes’s Theorems in the plane. Area of a surface. Integral of a vector field on a surface. Gauss’s Theorem. Stokes’s Theorem.

You can skip section 3D and the whole of section 6.

Here’s a list of exercises from the REVIEW at the end of each chapter which might be useful to do before the exam:

Chapter 1 (pp. 44-45): 17-26 and 31-35.
