Question

Find derivative of x by first principle method.​

Answer 1

Answer:

Derivative by First Principle:-

A derivative is simply a measure of the rate of change. It can be the rate of change of distance with respect to time or the temperature with respect to distance. We want to measure the rate of change of a function y = f ( x ) with respect to its variable x .

Derivative of a constant is always 0.

y=x

dy /dx

=d(x)/dx
