This applet generates random sinusoidal waves that can be modeled with a function of the form [color=#1551b5]y = a sin(bx - c) + d[/color] OR [color=#c51414]y = a cos(bx - c) + d[/color]
Students' job is to determine a correct set of parameters (a, b, c, & d) so that the graph of the trigonometric function they create matches the graph displayed on the screen.
[b]There are INFINITELY MANY CORRECT PARAMETERIZATIONS of the function displayed. Students are encouraged to create a few possibilities within this applet. If a student's model is correct, the applet will immediately indicate this.
[/b]
Students enter in EXACT (not approximate) values of parameters. (For ex, 2*pi/15 is simply entered as "2pi/15" in the inputbox.)
