$derivdef\left(65.9734457\sin\left(4\right)\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of y=21*pisin(4) using the definition. Multiply 21 times \pi . The sine of 4 equals . Multiply 65.9734457 times -0.7568025. Find the derivative of -49.9288687 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 -49.9288687. Substituting f(x+h) and f(x) on the limit, we get.
