Explain differentiation clearly in brief point to point

Dear Student,

Differentiation is the process of determining the derivative of a function at any point.
It is the instantaneous rate of change of a function with respect to one of its variable.

Let y = f(x) be a function of x. Then, the rate of change of “y” per unit change in “x” is given by:  ddxy=ddxf(x)
Few examples:
​​​​​1. If y = xn, ddxxn = nxn-1
2. If y = kxn, ddxy = nkxn-1   (here k is a constant)
