Where L is the width of the box (m), and n is a quantum number.

To graph a wavefunction enter the parameters (i.e., L, n) and hit New Plot. Up to 5 plots can be displayed at one time. The Clear button will remove all plots. To see the parameters for each plot hit the Legend on/off button. The Redraw button will refresh the graph. This is useful when the function domain (i.e., x ) has been changed. To see the value of each plot at a given point, move your cursor to the desired location then click and hold. Toggle between a plot of f(x) or f(x)² by clicking its radio button.
