Could somebody give me a step by step rundown?
Differentiate using the chain rule. The original equation is x^2 + y^2 = 25
So far, I've got:
1/2*(25-x^2)^-1/2 * (2x)
which apparently turns into
The book isn't telling me how to get from step to step, it's just showing me. I can't seem to figure out the algebra for this one.
