$derivdef\left(a-1\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of (a-1)^1/2^2 using the definition. Cancel exponents \frac{1}{2} and 2. Find the derivative of a-1 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 a-1. Substituting f(x+h) and f(x) on the limit, we get. Factoring by -1. Subtract the values 1 and -1.
