Homework Statement:
 2 AC waveforms are described by the following expressions (see equations), if V3 is the resultant combination of these waveforms find the following. Use angles as a decimal using a minus sign if appropriate.
Relevant Equations:

V1 = 160sin(1800 pi t)V
V2 = 180sin(1800 pi t  pi/3)V
I have calculated V3 to be 294.62sin(1800 pi t + 0.56)V
I am confident this is correct but I now need to work out the frequency of the waveform, I believe it may be 900 but I am not too sure if my calculations are correct and I cant find anywhere on line that aids me in this particular instance.
