Question

Find the rectangular coordinates of the point with the given coordinates.

(-4,-pi/3)

Answer 1

Please draw this point, so that you'll know whether the corresponding coodinates in cartesian coordinates is / are positive or negative. I see that your point is located in QII. (But check this for yourself!!)

Use the relationships\[x=r \cos \theta ~ and ~ y=r \sin \theta \] to find the x- and y-coordinates of this point.

Answer 2

here is a very rough drawing, but is this a correct drawing? i've got it left 4 and according to the unit circle it it should be on the opposite of pi/3
