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.
