$derivdef\left(xt+12t\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of sqr=t(x+12) using the definition. Multiply the single term t by each term of the polynomial \left(x+12\right). Find the derivative of xt+12t 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 xt+12t. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term x by each term of the polynomial \left(t+h\right). Multiply the single term 12 by each term of the polynomial \left(t+h\right).
