$derivdef\left(0+436\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of 639+436+-639 using the definition. Subtract the values 639 and -639. Add the values 0 and 436. Find the derivative of 436 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 436. Substituting f(x+h) and f(x) on the limit, we get. Subtract the values 436 and -436.
