Investigate the change in the graph of a sinusoidal function of the form and=sin x or and=cos x when multiplied by a polynomial function. Use a graphing calculator to sketch the graphs of and =2x, and =-2x, and=2x cos x on the same coordinate plane, on the interval [-20, 20].

Question

Investigate the change in the graph of a sinusoidal function of the form

and = \sin x or and = \cos x

when multiplied by a polynomial function. Use a graphing calculator to sketch the graphs of and

= 2 x, and = - 2 x, and = 2 x \cos x

on the same coordinate plane, on the interval

[- 20, 20] .
