Actually, I didn't find the derivative of the first term of the first term.

Sin (2xy) I simply put as Cos (2xy). Why are you taking the derivative of the inside function ? - Nov 8th 2009, 02:04 PMe^(i*pi)

Chain rule, just as e^i*pi said. Always remember to use the chain rule whenever you see a function in the parenthesis. If it isn't just , then you have to apply the chain rule. In this case, you have to apply a combination of the chain rule and implicit differentiation. So try to find the derivative

Oh. Whenever it isn't x...I think I get it.

Okay, that should be:

...Right ? - Nov 8th 2009, 02:22 PMadkinsjr

So do you understand how I found the derviative of

???

That one is kind of confusing. Other than that, the right side of the equation is very basic. I'm sure you can figure that out. So now you just have to solve for . - Nov 9th 2009, 02:41 PMStarlitxSunshine
Yup Yup, Sorry :33

I understood that part & was able to finish the question myself.

Thank you very much =)
