y=(-(1 - cos x)^(1/2)*1/2*(1 + cos x)^(-1/2)*sin x - (1 + cos x)^(1/2)*1/2*(1 - cos x)^(-1/2)*sin x)/((1 - cos x)^(1/2)^2)

I calculated it using a program. I would use the chain rule and quotient rule. But, I'm not sure if there's an identity you can use...

By the way, how do you guys write the equations using the fancy d/dx and stuff...
