Question

Consider a wave travelling through a medium that is $2$ metres long and has a thermal conductivity of $c=0\mathrm{.}13.$

Initially the wave has no amplitude, but the initial rate of change of the wave's amplitude $($with respect to time$)$ is a perfect sine wave $($a single oscillation the exact length of the medium$).$ Furthermore, the wave's amplitude is fixed at bc

ends of the medium.

Find the amplitude of the wave at the $x-$coordinates and times in the table below $($using $92$ terms of the infinite sum$).$ Fill out the table below with your answers.
