Homework Statement



if x^2*y-e^2x=sin(y) find dy/dx


The Attempt at a Solution



I tried solving for y but that seems quite impossible so I was wondering if anyone had any other suggestions on possible solutions. Thanks

Do you know what implicit differentiation is?
 
yes...thanks for reminding me of that. the left side isn't a problem but how do you differentiate sin(y) with respect to x?
 
actually wouldn't it just be 0? then dy/dx is e^2x/x
 
You have sin(y). y is a function of x so you could write this as sin(y(x)). Then use the chain rule
