Both of the highlighted equations deal with a standing wave. However, they are slightly different in the sense that the latter has a phase shift in it.
Why ?
Also, how does one go from the latter equation for a standing wave to :
2A*sinkx*sinwt. For a string with both ends fixed
And
2A*sinkx*coswt. For one end fixed and the other free
And
2A*coskx*coswt. For both free.
