Question

A string of length L is stretched along the x-axis and is rigidly clamped at its two ends. It undergoes transverse vibration. If n is an integer, which of the following relations may represent the shape of the string at any time : -

Options

A.y = A sin cosωt
B.y = A sin sinωt
C.y = A cos cosωt
D.y = A cos sinωt

Solution

y = 0 at x = 0.
This can be satisfied by the term sin
