Combinations: Product and Quotient

Three adjacent windows display graphs of (1) a function \(f\)  and its derivative, (2) a function \(g\) and its derivative, and (3) a function \(h\) and its derivative. From a drop-down menu, \(h\) is defined to be the sum, product, or quotient of \(f\) and \(g\). The functions \(f\) and \(g\) can be freely defined by user.
