$derivdef\left(0.7539023\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of sin(47)+sin(61)-sin(11)-sin(25)=cos(7) using the definition. The cosine of 7 equals . Find the derivative of 0.7539023 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 0.7539023. Substituting f(x+h) and f(x) on the limit, we get. Subtract the values 0.7539023 and -0.7539023. Zero divided by anything is equal to zero.
