Slader consider an elastic string of length l whose ends are held fixed. the string is set in motion with no initial velocity from an initial position u(x, 0) = f(x). let l = 10 and a = 1 in parts (b) and (c). (a computer algebra system is recommended.)

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?
