i am getting 2m(r^2)(ln(R)/(pi) - m((cos(theta))^2)(R^2)/(2pi)

i am not sure too..............are getting the same???

This is wrong, putting \(\theta = \pi/2\) does not yield \(\frac {mR^2} {2}\)

You can check by putting θ=0

@Karan Shekhawat I have a guess \[I= mr^2 \cos^2 \theta +\frac{mr^2}{2} \sin ^2 \theta \]
