Use implicit differentiation to find dy/dx. e^4x = sin(x+2y).

This is a practice problem. It says the correct answer is 4e^x/(2sin(x+2y)) but I keep getting 4e^(4x)/(2cos(x+2y)).

I thought the derivative of e^(4x) would be 4e^(4x), not 4e^(x).

And I use chain rule on sin(x+2y) but I get cos(x+2y) * 2dy/dx.

Help would be appreciated, thanks!
