Question

How do you convert the polar coordinate `(-9.028 , -0.663)` into rectangular coordinates?

Answer 1

`(-7.12,5.56)`

Explanation:

To convert from polar coordinate to rectangular coordinate we use the formula `x=rcos theta, y=rsin theta`

Hence,

`x=-9.028cos (-.663)~~-7.12`

`y=-9.028 sin (-0.663)~~5.56`

So the point is approximately `(-7.12,5.56)`
