Hi :)

I am currently studying for an electronics exam and I have come across an op-amp RC phase shift oscillator question which I am having trouble with. In this question we are required to find the loop gain characteristics of the circuit. I have tried many times but still cannot get the answer. The question along with the circuit has been included with this post.

Any help would be greatly appreciated. My exam is in two days time so I am getting really desparate for help.
