$derivdef\left(30\frac{1}{2}\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of cos(15)=301/2 using the definition. Divide 1 by 2. Multiply 30 times \frac{1}{2}. Find the derivative of 15 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 15. Substituting f(x+h) and f(x) on the limit, we get. Subtract the values 15 and -15.
