Question

Find the rectangular coordinates of the point with the polar coordinates (3, 3/2 pi).

(0, 3)

(0, -3)

(-3, 0)

(3, 0)

Answer 1

I like degrees rather than radians. can you change the angle to degrees ? (by multiplying by 180/pi)

Answer 2

(3,270) @phi

Answer 3

now look at my picture in the earlier question and find angle 270. start at 0,0 and draw a line 3 units long. what is the (x,y) coordinates of the end point of the line?

Answer 4

3,3 @phi

Answer 5

where do you get (3,3) ? the angle is 270, so the answer has to be on the 270 line
