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) ?

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

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

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) ?

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.
