Consider the point $(x,y)=$(1, $\sqrt{3}$) plotted in the graph below. (a) Find the value of $r$ in the equivalent $(r,\theta)$ polar coordinates.
(b) Now that we have the values of $x$, $y$, and $r$, which of the following equations could help us solve for $\theta$?


(c) Use one of your answers to part (b) to find a possible value of $\theta$ between 0 and $2\pi$.
(d) Which of the following are also possible values of $\theta$?


(e) Find all possible values of $\theta$.
$\theta=$ + $\cdot k$
where $k$ is any integer and the base angle is between 0 and $2\pi$.
