Investigate the change in the graph of a sinusoidal function of the form \(\displaystyle{\quad\text{and}\quad}={\sin{{x}}}\) or \(\displaystyle{\quad\text{and}\quad}={\cos{{x}}}\) when multiplied by a polynomial function. Use a graphing calculator to sketch the graphs of \(\displaystyle{\quad\text{and}\quad}={x}^{{{2}}},{\quad\text{and}\quad}=−{x}^{{{2}}}\) and \(\displaystyle{\quad\text{and}\quad}={x}^{{{2}}}{\sin{{x}}}\) on the same coordinate plane, on the interval [-20, 20].
