$derivdef\left(1^4\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of y=sec(0)^4 using the definition. Calculating the secant of 0 degrees. Calculate the power 1^4. Find the derivative of 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 1. Substituting f(x+h) and f(x) on the limit, we get. Subtract the values 1 and -1.
