## MATH 251 - Suggested Homework

Text: *Calculus, with Early Vectors*, Preliminary Edition, by James Stewart. Individual sections may vary somewhat from this schedule.

### Chapter 11

**Section 11.1 --**#3, 5, 7, 13, 25, 29, 31, 33, 35, 39, 45, 47.**Section 11.2 --**#5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 31, 33, 35.**Section 11.3 --**#3, 5, 7, 9, 11, 19, 21, 23, 31.- Also be able to do the following problem:

Let A_{1}and B_{1}be the vectors (1,2,0) and (-3,1,0), respectively. Let A_{2}and B_{2}be the vectors obtained by rotating A_{1}and B_{1}by an angle of 60 degrees in the counterclockwise direction about the Z-axis. Compute the vectors A_{2}and B_{2}and show that the cross product of A_{2}with B_{2}is the same as the cross product of A_{1}with B_{1}.

Hint: to compute A_{2}and B_{2}, express the x,y-coordinates of A_{1}and B_{1}using polar coordinates.

Answer: A_{2}=(-1.232, 1.866, 0); B_{2}=(-2.366, -2.098, 0) and A_{1}x B_{1}= (0,0,7) = A_{2}x B_{2}. **Section 11.4 --**#3, 7, 13, 15, 17, 19, 25, 29, 31, 37, 43, 47, 49, 51, 55, 63, 65.**Section 11.5 --**#1, 3, 5, 7, 9, 11, 15, 17-24, 31, 33, 41.
