Derivative of a trig function problem

[Math_Junkie]

I'm having trouble finding the following derivative:

My answer is:

h'(?) = -2csc(?)cot(?) + 4e[sup:1ka6az1p]?[/sup:1ka6az1p]cot(?) - csc[sup:1ka6az1p]2[/sup:1ka6az1p](?)4e[sup:1ka6az1p]?[/sup:1ka6az1p]

But it seems to be the wrong answer.

Any help appreciated greatly!

As far as I can see - your work is correct. May be the "on-line monster" wants it in a different form. Talk to your teacher.
