Find the derivative of the function y = 1 / X Find the derivative function of the following function y=1/x

Find the derivative of the function y = 1 / X Find the derivative function of the following function y=1/x

Y = V / u, then y '= (v'u-u'v) / u ^ 2
So if y = 1 / x, then y '= (1'x-x') / x ^ 2 = - 1 / x ^ 2
