A standing wave on a string is given by `y = ( 4 cm) cos [ x pi] sin [ 50 pi t]`, where `x` is in metres and t is in seconds. The velocity of the string section at `x = 1//3 m at t = 1//5 s`, is

The equation of a progressive wave is y =4 sin (4 pi t-0.04 x+pi/3) where x is in metre and t is in second. The velocity of the wave is
