    I am attempting to do a college assignment and i have forgotten everything about this, if we were even taught it to begin with!

    The question goes like this:

    "Determine the resultant of two sine waves, A at 150 volts and B at 100 volts leading by 60 degrees to give the resultant C using both graphical and phasor diagram methods"

    I am asking if someone can explain to me what this line of to me what sounds like gibberish actually means :)

    I would like help A.S.A.P as it has to be handed in tomorrow as i am going on holiday.

    I would be really really really greatful if anyone could help me, i hope my lecturer isn't on this forum :s

    It is not the answers i am looking for, it is just an interpretation of what that sentence means

    Graphically means draw the sine waves on the paper and by phasors it means represent the sine waves as phasors as to find the resultant sine wave.

    so do i just draw both Sine waves? what does it mean by resultant? do i need to add there totals together to get the C wave or something?

    That's exactly what resultant means --- add the two sine waves
    together. When you add together two sine waves of the same
    frequency (but possibly different phases and amplitudes), the
    result is a third sine wave of the same frequency. Your task is
    to determine the phase and amplitude of the sine wave which
    results from adding together the two given sine waves.
