How to differentiate 1/x^2 from first principle | y = 1/x²

In calculus, differentiation is one of the two important concepts apart from integration. Differentiation is a method of finding the derivative of a function. Differentiation is a process, in Maths, where we find the instantaneous rate of change in function based on one of its variables. The most common example is the rate change of displacement with respect to time, called velocity. The opposite of finding a derivative is anti-differentiation.

If x is a variable and y is another variable, then the rate of change of x with respect to y is given by dy/dx. This is the general expression of derivative of a function and is represented as f'{x} = dy/dx, where y = f{x} is any function.

In this video, Avitech maths will guide you on how to differentiate √x {root x} using first principle.

We can normally solve it like this :- y=1/x^2
Y=x^-2
Y=2x ^-2-1
Y=2x^-3
