$(1$ point$)$

A point $P$ moves along a circle of radius $3,$ as shown in the figure to the left, below.

The angle $,$ in radians, between the point's location and the positive $x-$axis is given as a function of time $t,$ by the graph in the second figure.

$($a$)$ What is the value of $$ when $t=2?$

$=$

$$

$($b$)$ Find the coordinates of $P$ when $t=2.$

Coordinates $=(3($i$)).$
