A simulation of the wave equation [math]\frac{\partial^2}{\partial t^2}u(t,x)=c^2\frac{\partial^2}{\partial x^2}u(t,x)[/math] on the interval [math][0,\pi][/math].[br][br]The initial condition (shape/position of the string at [math]t=0[/math]) can either be entered in the input box, or chosen from the drop-down menu.[br]The initial velocity is [math]0[/math], and the endpoints of the string are fixed.
