Precalc
Today we reviewed a little of 5.4-5.5 and then took a quiz on said material. This weekend, bue sure to review for Tuesday's test, and bring questions for Monday!
Notes:

Homework:
Textbook: pp455-456 #'s 4, 6, 19, 23, 24, 32, 34, 35, 40, 47
Problems not in textbook:
Suppose A = sin(x) and B = cos(x), and x is in QI.
Find the following in terms of A & B:
ex) sin(2x) = 2sin(x)cos(x) = 2AB
1) sin(x/2) 2) cos(2x) 3) sin(3x)-sin(x)
**If you are stuck or want to check over your work, Mr. Hurley has been nice enough to provide solutions for you here. (For real this time!)
