Solutions to the review exercises
3pi/4 = 2.36 radians
228 feet
sqrt(2), 2/sqrt(3)
even
no amplitude, period=pi, phase shift=pi/6
sqrt(2)/2
start with the LHS, then try LCD and simplify
sqrt(3)/2
start with the LHS, then use sum and difference identity of sine, simplify and done
use sum identities, double angle identities and the Pythagorean identity
x=2k pi, pi/6+2k pi, 11pi/6+2k pi, k is an integer
beta=22degree, gamma=128degree, c=7.88feet
angle between CAB=33 degree (use Pythagorean Theorem)
r=5sin(theta) and 3x-4y=-1
