The
bottom left graphing window shows a graph of a cos(ωt) in yellow
and a graph of b sin(ωt) in cyan. The top left window shows a
graph of the sum of these two functions in green, and a graph of A cos(ωt
- φ) in red.
Grab
the [a], [b], [A], [φ], and [ω] sliders to set these parameters.
Control
the display at right by means of the buttons below it, labeled [a,b] and [A,φ].
