# Math Help - sin graph

1. ## 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.

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

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

4. 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?
