WebAnswer: the derivative of cos(x)sin(x) = cos 2 (x) − sin 2 (x) Why Does It Work? When we multiply two functions f(x) and g(x) the result is the area fg: The derivative is the rate of change, and when x changes a little then both f and g will also change a little (by Δf and Δg). In this example they both increase making the area bigger. WebFeb 15, 2024 · So, the derivative of x^2 is 2x! But what does the power rule apply to more complexity work?.
