You don't need to. You can just look at the equation and see the amplitude and period from there. Like if you have y=3sin (πx), you can see that the amplitude is 3, and you can just divide 2pi by pi to see …

Amplitude can be measured rather easily in pixels. In the case of a window 200 pixels wide, we would oscillate from the center 100 pixels to the right and 100 pixels to the left.

To be specific, amplitude is defined to be the magnitude of the displacement from the equilibrium center line to the top of a crest. Since the amplitude is a magnitude (and therefore positive by definition), …

Sal introduces the main features of sinusoidal functions: midline, amplitude, & period. He shows how these can be found from a sinusoidal function's graph.
