    There is no value of theta in cos(theta) that would equal 4. So you are right, it is undefined.

    Your equation equals \[(sinx+1)(sinx+1)=0\] Understand how I got that? And know how to solve this?

    Yes, you factored it. I solved it. It is 3pi/2, right?

    Yea, that is the only theta in the interval [0,2pi] where sinx=-1
