Question
Sketch a graph with a table for the following equation.
![The equation displayed is:
\[ r = \cos 2\theta \]
This is a polar equation. In polar coordinates, \( r \) represents the distance from the origin to the point, and \( \theta \) is the angle measured from the positive x-axis. The equation \( r = \cos 2\theta \) describes a specific shape known as a "rose curve," which typically has petals that are symmetrically distributed around the origin. The number of petals in the rose curve is determined by the coefficient of \( \theta \). Here, with a coefficient of 2, the curve will have 4 petals.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6a85ba4d-6f5c-41bf-97e5-182adb23b838%2F5c14bb85-1819-422e-90db-4691e05dae9c%2Fbqw6cf7_processed.png&w=3840&q=75)
