    What will be the graph of v=Vmsin(wt+theta) and v= Vmsin(wt-theta) and why?:oldconfused:

    For what value(s) of x does sin(x)=0 ? For what value(s) of x does sin(x+1)=0 ? What does adding 1 to x do to the graph of sin(x) ?

    The graphs will be two sine waves of equal magnitude Vm, with a phase difference of 2θ.

    Don't forget the w.

    sin(x)=0 when ##x=0## or ##x=\pi##
    sin(x+1)=0 when x+1=##0## or ##x+1=\pi##

    Tell us what you think adding 1 does to the graph.

    Function translation.
