A plot cell graphs an expression in the single variable x, sampled across a range you set. Keep the plotted expression unitless and use x as the horizontal axis; everything else (amplitude, frequency) can be a variable you defined above.

amplitude=2amplitude = 2 try 0.5, or 4
amplitude * sin(x)
-101-505

y = amplitude · sin(x) — edit amplitude and the curve restretches
