can u explain to me step by step of finding the derivative of a function x√(x-1) using four step rule .. big tnx in advance..
I think these are the four steps that iamjhay is talking about:
1. Write and
We would call it computing the derivative from the definition.
To iamjhay: I think this identity will get you over the difficult part:
