This document discusses rules for taking derivatives of sums, products, powers, and quotients of functions. It provides examples of applying the power rule to take the derivative of x^3 as 3x^2. The product rule is defined as the derivative of f(x) * g(x) being f(x) * g'(x) + g(x) * f'(x). An example applies this to the functions f(x)=2x and g(x)=x+3. The quotient rule is defined as the derivative of f(x)/g(x) being (g(x)f'(x) - f(x)g'(x))/g(x)^2.
