How to plot waveforms

I have this question in my assignment and i have no idea how to do it. how do you ploy waveforms is there a program? the question is:

Two ac voltages are represented by
V1=20sin(w)t volts and v2 = 01 sin ((w)t+pie/3)

(w) is the angular frequency symbol i think

and i have to plot waveforms of v1 and v2 on the same axes using the same scale over one cycle (15degree interval)
the questions go on but i have no idea how you would plot this , is there some kind of program ? and info if helpful
thanks.

There is no program that you need, The equations state that the waveforms are 'sin' or 'sinusoidal' is the full term. It means that the output varies and oscillates in a certain way, as explained by wikipedia

http://en.wikipedia.org/wiki/Sine_wave

For V1, the amplitude of the wave (the highest height reached by the curve), as measured on the y-axis, is 20, and the wave starts at 0 on the x-axis.
For V2, the amplitude is 01, although I imagine you meant to type 10? :)
The 'pi/3' is called the 'phase difference' which means that when you draw the wave of V2, it's starting point is further along the x-axis than V1, it's starting point is between the start of the V1 wave and the first maximum amplitude, but I can't draw it here. I hope that helped and wasn't too complicated :D
