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
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
