Question

What is the polar form of `( -23,0 )`?

Answer 1

`(23;pi)=23/_pi`

Explanation:

This point lies on the negative x-axis, 23 units left of the origin.

Hence its length from the origin is `r=23` units and its angular displacement from the positive x-axis is `theta=180^@=pi` radians.

Hence the polar form is `(23;pi)=23/_pi`
