Consider the polar curve defined by the function r (theta=theta cos (theta where 0 is less than or equal to theta and theta is less than or equal to 3pi/2

Given:

The function:

r (θ) = cos θ

where θ ≤ 3π/2

In the polar coordinates, we need to convert 3π/2 to degrees:

3π/2 = 3*180/2 = 270 degrees

This means that the function should be less than of equal to 270 degrees.
