The Attempt at a Solution

i really don't know how to start this off.
i know some working should be done in order to sketch it but what?

If you were sketching a graph in the Cartesian plane (x,y), how would you do it? You'd pick some x points, calculate the y value, and plot the points, and then infer the shape of the curve from that.

It's no different here. Let t take on a number of values in its domain, and calculate r. Then plot those points in polar coordinates.
