    Sine Wave Addition

    I'm sorry but I'm still confused. If y1 = Asin(kx-wt+phi) and y2 = Asin(kx+wt) the addition is y= 2Acos(wt-phi/2)sin(kx+phi/2) where phi is the phase shift between 0 and 2pi. Does this still fit the standing wave equation y=(2Asin(kx))cos(wt) meaning its a standing wave or does the difference...

    Sine Wave Addition

    As far as i can see it doesn't say anything about phase shift so does that mean it doesn't affect anything?

    Sine Wave Addition

    If two sine waves have the same frequency and amplitude but have different phase shift do they still produce a standing wave? Thanks for the help.
