Work Step by Step
The question ONLY asks for a graph of the polar equation.
Given $r = -\cos 5θ$
Table of Values:
$(-1, 0)$
$(-1/2, \frac{\pi}{15})$
$(0, \frac{\pi}{10})$
$(1/2, \frac{2\pi}{15})$
$(1, \frac{\pi}{5})$
$(1/2, \frac{4\pi}{15})$
$(0, \frac{3\pi}{10})$
$(-1/2, \frac{5\pi}{15})$
See graph below. It is in the shape of a flower/rose.
