(a) A string of length L is stretched and fastened to two fixed points. The displacement of the string is given as Satu tali dengan panjang L diregang dan ditetapkan kedudukannya pada dua titik tetap. Sesaran tali diberikan sebagai u (x, 0) = The string is released with zero velocity. By applying the equation 02 with c2 1 and using the separation of variable method, a c2 at2 determine the subsequent motion u(x, t). Tali dilepaskan pada halaju sifar. Dengan...
