Question

How to identify polar angles and reference angles to polar angles.

Answer 1

Answer:

See below

Step-by-step explanation:

To convert from Cartesian coordinates $(x,y)$ to polar coordinates $(r,\theta)$, use the following formulas:

$r=\sqrt{x^2+y^2}\\\theta=tan^{-1}(\frac{y}{x})$

Reference angles are the acutes angles that the terminal side of $\theta$ makes with the x-axis.
