Learn how to solve definition of derivative problems step by step online. Find the derivative of (4+5)^1/2 using the definition. Add the values 4 and 5. Calculate the square root of 9. Find the derivative of 3 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 3. Substituting f(x+h) and f(x) on the limit, we get. Subtract the values 3 and -3.
