From d'Alembert's solution for the one dimensional wave equation
A string of length l=1 is initially fixed i the position [itex] u = \sin{\pi x} [/itex] and is released at time t = 0 . Find its subsequent motion
What do they mean by the subsequent motion?? DO they mean the velocity? Do i differnetiate u by time? the answer i know is [itex] u = \sin{\pi x} \cos{ \pi ct} [/itex]
ANd where di they give the c from anyway? The intial u represents the soltuion with the integral part of d'Alembert's soltuion equal to zero, doesn't it?
Please help! Thank you!
