@agent0smith

Answer 5

sine has a period of 2pi. so any f(x + 2pi) = f(x) for all x

Answer 6

oh, well, that was wrong. it was -A

Answer 7

When in doubt, look at your unit circle.

Answer 8

O.O oh crap I was thinking about cosine :D

Answer 9

haha that's alright :) i had the opportunity to correct the question

Answer 10

sin(2pi - x) = sin(- (x + 2pi) ) = - sin(x + 2pi) = -A

:D
