1. Find sec(
) exactly

2. Recall, P( ) = (cos , sin )
Let
=
+
P( + ) = (cos( + ), sin( + ))
Sum + Difference Tougher

a) sin( + )
b) cos( + )
c) Coordinates of P( + )
d) Quad of P( + )
e) tan( + )

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