Find dy/dx

Problem in picture below

2. Relevant equations

3. The attempt at a solution

The answer for this is

dy/dx = [tex]-cos\theta sin\theta + (1-sin\theta)cos\theta[/tex]/[tex]-cos^2\theta - (1-sin/theta)sin\theta [/tex] I cannot figure out why I'm not getting the same or equivalent for dy/dtheta.... and trig makes me woozy.
