Homework Help: Pre-Calc

Posted by Katie on Saturday, June 7, 2014 at 11:51pm.

2. The polar coordinates of a point are given. Find the rectangular coordinates of each point.
a. (5,(π / 4))
b. (-2,(π / 6))

NOTE: I tried to do these myself and got that:
a= (4.99,0.27)
b=(-1.99,-0.11)

Which I know these are wrong, so I don't know how to do them..
