Learn how to solve definition of derivative problems step by step online. Find the derivative of 1/5(-7^(-1)+112^(-1)) using the definition. Divide 1 by 5. Find the derivative of \frac{1}{5}\cdot \left(- 7^{-1}+112^{-1}\right) using the definition. Apply the definition of the derivative: \displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}. The function f(x) is the function we want to differentiate, which is \frac{1}{5}\cdot \left(- 7^{-1}+112^{-1}\right). Substituting f(x+h) and f(x) on the limit, we get. Cancel like terms \frac{1}{5}\cdot \left(- 7^{-1}+112^{-1}\right) and -\frac{1}{5}\cdot \left(- 7^{-1}+112^{-1}\right). Zero divided by anything is equal to zero.
