Question 1: Write the polar coordinates (with r > 0 and 0 </= theta < 2pi) for the point with rectangular coordinates (0, 3).

Question 2: Write the rectangular coordinates (x, y) for the point with polar coordinates (5, pi).

My work for #2:

x = 5 cos (pi) = 0

y = 5 sin (pi) = 5

Rectangular Coordinates: (0, 5)

Is this right?

I am really confused on these questions.

Any help is really appreciated.
