W Feb 24 Sec. 15.7
Review problems for Exam 2 Please solve thse problems by Friday. Thes solutions will be discussed in lecture.
F Feb 26 Review of Sec. 14.7 to 15.7
Midterm 2 - Monday, March 1 in Pomerene Hall 306 Note the place for the midterm!
W March 3 15.8
F March 5 16.1, 16.2 (up to Example 3)
W 16.3 only: Theorems 2 and 5, the fact that the integral of a conservative field is independent of path, and its integral over a closed curve is zero,calculation of the potential of a conservative field.
Final exam information:
Tu March 16 at 11:30 in Pomerene Hall 306
You are allowed to bring and use a page (written on both sides) with your own notes.
A few review problems (Note: in problem 1: solve first 1b and then 1a with the solution of 1a being: since F is conservative then the integral is path-independent.)
I am grateful to Siva for supplying corrections to calculation errors in the solutions to the review problems (and to Jillian for pointing them out). Here they are: 1c. 1+1+3-0=5 and not 3; 2. sqrt(10) should be sqrt(11). 3. cos(theta) was mis-copied below as cos(phi) so the final answer should be zero (Why does zero make sense?) 6b. df/dy should be replaced by its correct value. 6c. the answer is like in the midterm and midterm review problems. As I said in class, these are my notes containing problems to go over in class, and I was not thorough or careful in writing up the solutions, and they do NOT represent a model of how your solutions should look like when written up
Research opportunities at OSU: MBI Summer Undergraduate Program
June 21 - July 2, 2010 Location: Mathematical Biosciences Institute, The Ohio State University
This program consists of two parts: (a) two weeks of introductory lectures plus short projects and a computer lab, and (b) a summer long research experience (6 weeks to be followed immediately after the 2 weeks) devoted to projects in the interface of mathematics, statistics, and biological sciences. The summer long research experience for undergrads (REU) will begin July 5, and the presentations will be August 13, 2010.
