The polar coordinate equation:r=cos (θ/3) +1/9 is drawn in different windows with four drawing methods using the Graph window segmentation method.

Solution:MATLAB directive:

Theta=0:0.1:6*pi;rho=cos (THETA/3) +1/9;

>> Polar (Theta,rho)

>>

>> plot (Theta,rho)

>> SEMILOGX (Theta,rho)

>> Grid

>> hist (rho,15)

The results were as follows:
