Find the derivatives of the following functions at the indicated points : x at x = 1

Philoid · Accepted Answer

Derivative of a function f(x) at any real number a is given by –

{where h is a very small positive number}

∴ derivative of x at x = 1 is given as –

Hence,

Derivative of f(x) = x at x = 1 is 1
