1. Recall, P( ) = (cos , sin )
Let = +
P( + ) = (cos( + ), sin( + ))
Sum + Difference Tougher
Given cos = 4
sin = 12
where P( ) is in quad 1 and P( ) is in quad 2
a) sin( + )
b) cos( + )
c) Coordinates of P( + )
d) Quad of P( + )
e) tan( + )

2. Given sin = 3
cos = -12
where neither is in quad 2
a) sin( + )
b) cos( + )
c) Coordinates of P( + )
d) Quad of P( + )
e) csc( + )
