To determine

To state: that how to convert from polar coordinates to rectangular coordinates.

Answer to Problem 4CFU

To convert the polar coordinates to rectangular coordinates, substitute $x=r\cos \theta \text{ and }y=rsin\theta$ and then substitute and simplify.

Explanation of Solution

Given information:

Convert polar coordinates to rectangular coordinates.

to convert the polar coordinates to rectangular coordinates, substitute $x=r\cos \theta \text{ and }y=rsin\theta$ and then substitute and simplify.

Thus, the value of $\left(x,y\right)$ is the rectangular coordinates for polar coordinates.
