    sin graph

    i have been give two formula to work out V1 and V2. Both contain sin and should create a waveform and i need to find the phase angle between the curves. i know how to do this, but after atempting to work out the graphs they are not correct can anybody help me? (see attachment for my incorrect effort)
    (pi = 3.141 dont have symbol)
    V1= sin (T+pi/3)
    V2= sin (T-pi/4)
    T ranges from -pi/2 to 5pi/2
    the figures must be shown on a graph.

    Phase angle between? Wouldn't that be \frac{\pi}{4}+\frac{\pi}{3}=\frac{7\pi}{12}?

    The distance between relative maxima is
    \frac{3\pi}{4} - \frac{\pi}{6} = \frac{7\pi}{12}

    thanks that graph is really helpful, but i don't understand how you got pi along the X axis. do i have to rearrange the formula or something?
