using the first principle of differentiation, find the first derivatives of

f(x) = 3/x^{2}and 1/(sqrt x)^{3 - if using product rule i know, but if using first principle, my ans not the same. Please help me. }

How far can you get? Do you know what you are trying to find the limit of?

Did you hear about this formula

This is called differentiation from first principles, (or the delta method). It gives the instantaneous rate of change of y with respect to x,
