### Example Question #2 : Polar Form

What is the following coordinate in polar form?

Provide the angle in degrees.

**Possible Answers:**

**Correct answer:**

To calculate the polar coordinate, use

However, keep track of the angle here. 68 degree is the mathematical equivalent of the expression, but we know the point (-2,-5) is in the 3rd quadrant, so we have to add 180 to it to get 248.

Some calculators might already have provided you with the correct answer.
