Question

How do you convert `(-2, pi)` to rectangular form?

Answer 1

(2,0)

Explanation:

First draw angle `pi` as shown below. Now r=2 would be along the terminal side of `pi` and -2 would be just opposite to r=2. This would lie on positive x axis in the first quadrant as shown in the figure `(-2, pi)`. The rectangular form of the coordinate would therefore be (2,0)
