Question

Convert the polar coordinates (-83,23°) into rectangular coordinates. Round the trigonometric values and the rectangular coordinates to the nearest hundredth.

Answer 1

just plug in your transformations
x = r cosθ
y = r sinθ

Answer 2

-83[23o] = -83*Cos23 + (-83*sin23)i = -76.40 - 32.43i.

Answer 3

Thanks Oobleck and Henry2 I got it now!

Answer 4

actually, you don't need the "i" stuff unless you want to represent the point as a complex number.
the polar point (-83,23°) is the x-y point (-76.40, - 32.43)
