# How do you convert #(-2,0)# from cartesian to polar coordinates?

Polar form:

Given:

Cartesian coordinates:

How do we convert from Cartesian coordinates to Polar form?

Polar Form:

Examine the sketch below:

Important formula to remember:

Let us identify the point on the Cartesian Plane:

Cartesian coordinates:

Note that the angle is

Hence

Use the formula:

Swap sides:

Taking the

Hence, the required Polar form:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
