(a) The energy in an infinite string with no external forces is given by E(1)=(Sw + Tw) dx. Show 0 and hence E(t) = E(0). You may assume that lim, >100 x = 0. (b) If show E(t)=T. y(x, 0) = f(x) = {o 1-x, x1 >1 V(x,1)=0, (a) The energy in an infinite string with no external forces is given by E(1)=(Sw + Tw) dx. Show 0 and hence E(t) = E(0).
