Question 978390: I have a question on Applications of Trigonometric Functions and Polar Coordinates.

Third question is polar coordinate points are given convert them into rectangular coordinates:
(-2, 3/4pi) (7.5, 110 degrees)

I have the answer in the back of the book but i need help trying to get to the answers. It would be great if you can help me solve them before tomorrow night, which is when my test is.
