i have used the formula.. zy/zt =wAcos((kx - wt + (beta)) and solved for beta. i got an answer 0.78 and it was wrong.

Propagating wave find initial phase angle?? A wave is propagating down a string having a diameter of 0.0013 m and a density of 5240 kg/m3. The wave has the form y = A sin(k x - w t + beta) where A = 0.011 m, w = 59.8 rad/s, and k = 72.4 rad/m. the velocity of propagation of the wave is...
