## Prerequisites

You should be comfortable with single-variable integration and differentiation, partial derivatives, and basic properties of vectors (doing arithmetic with them, dot product, cross product, etc.). We'll also use double (and triple) integrals often, so you may want to refresh yourself on those if necessary, but we'll cover them again in any case.

Several ideas in this course are best seen through the lens of linear algebra. If you don't know anything about linear algebra, don't worry, it's not a prerequisite and I won't assume any knowledge of it. But if you do, it might be worth reviewing a few things, since there will be times I'll take a minute or two to give an additional linear-algebraic explanation of something. In particular, matrix multiplication helps to demystify the chain rule in multiple variables, and the geometric properties of determinants explain the change of variables formula for multiple integrals.

## Announcements

• A new extra credit problem has been posted.
• The final exam is Wednesday, June 6 for section A, and Thursday, June 7 for section D. Both of them are 8:30-10:20, NOT at the usual class time! They are in the usual rooms.
• You can find links to two sample finals, with solutions, here: (one), (two). Finals are more uniform than midterms, since there's no issue about getting to different material at different times, so if you have the time, it would be worthwhile to actually take one of these and see how it goes.
• I'll have extra office hours next week (finals week), Monday 3-5, in addition to the usual Tuesday 3-5.
• Final exam review
• Final exam solutions: section A, section D.
• I'll be in my office Tuesday 3-5 if you want to come look at your final.

## Old announcements

• The syllabus.
• Here's some information on using Webassign. This is from a past class, but everything there should still apply here.
• Homework 1 is on Webassign; due Tuesday, April 3 Wednesday, April 4 (Thursday at 6 am).
• Homework 2 is on Webassign, due Tuesday, April 10. Note: I absolutely don't care if you use a computer to do the integrals on the 2 homework problems from 15.5, though if you feel like you want practice integrating that's good too. If you do the second one by hand, polar coordinates would be convenient, so I only request that if you do use a computer, you at least set up that integral in polar.
• Midterm 1 will be Friday, April 20.
• There's an extra credit problem, see here.
• Here are some old midterms with solutions:
• Office hours this week will be Thursday (April 19) 1:30-3:30.
• Here's an 3d graphing tool which you can download or run online.
• Solutions to Midterm 1
• There's a solution to the first extra credit problem.
• Midterm 2 will be Friday, May 18.
• Midterm 2 review.
• A new extra credit problem has been posted.
• Here are some sample exams/problems to look at for Midterm 2:
• Solutions for Midterm 2.
