|Explore the Equation grapher simulation (below) for several minutes:
- The axes of the graph are indicated by black lines and labels x and y.
- The black "tick" marks represent a magnitude of 1 from the origin (0,0).
- The sinusoidal function [math] f(x) = a\, cos( 2 \pi\, (b x + c) ) [/math] is represented by the red line.
- Try clicking check boxes
- Try sliding sliders
- Try entering number in textboxes
When you have finished exploring try the multichoice question. Once you have completed the multichoice question try one of the main activities.
