Thread: Differentiation problem

If x^2 + y^2 = 2y , find dy/dx in terms of x and y without first finding y in terms of x.
The prove (d^2 y/dx^2) = 1/[(1-y)^3]
I'm confused as to what happens when you differentiate y^2 and 2y : is it - y^2 dy/dx and 2y dy/dx?

Read this, all will be clear..

Yep,got it now. Thank you
