$derivdef\left(-1\cdot pi_1^3\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of (-pi_1)^3 using the definition. Simplify \left(- pi_1\right)^3 by taking the minus sign (-) out of the power. Find the derivative of -1\cdot pi_1^3 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\cdot pi_1^3. Substituting f(x+h) and f(x) on the limit, we get. Multiply -1 times -1. Cancel like terms -1\cdot pi_1^3 and pi_1^3.
