Derivative of cos x /x

WebAnswer: the derivative of cos (x)sin (x) = cos2(x) − sin2(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.
