We know that the derivative of a function is written as f'(x)
It refers to that the function is a derivative of y concerning the variable x
Consider f(x) = 1/x = x-1
So by differentiation
f'(x) = n xn - 1 , where n = -1
Let us replace the value of n as - 1
f'(1/x) = -1 x-2
f'(1/x) = -1/ x2
Therefore, if someone asks you to Find the derivative of 1/x, then the answer will be that the derivative of 1/x is -1/ x2
Summary:
Find the derivative of 1/x.
The derivative of 1/x is -1/ x2
