Calculus Derivatives and Rules

The video tutorial explains how to find the derivatives of two functions, g(x) and h(x), using the product and quotient rules of differentiation. Given specific values for f(pi/4) and f'(pi/4), the tutorial walks through the steps to calculate g'(pi/4) and h'(pi/4). The product rule is applied to g(x) = f(x) * sin(x), and the quotient rule is applied to h(x) = f(x) / cos(x). The tutorial provides detailed calculations and simplifications to arrive at the final results for g'(pi/4) and h'(pi/4).
