Given the string vibration problem as follows: t and on the right hand end of the Length of the string is equal 8, tension is 10 and dense is equal 1. The displacement of the left hand end of the string is equal string it is given a force equal 0. ➤ At initial form of the string is given as 3sin- +5sin. ➤ At initial speed is equal 7sin+8sin- + 64 11x 16 16 9πx 16 9x (x-8)2 16 ➤ There is a force acting on the string expressed by the function 5t 7πχ 7sin- - 16 16
