Can someone tell me how you would plot a cos function into matlab so that you can see a few periods of the graph? I am trying to graph
v(t)= 5.6576cos(377t+44.9945)
where the 44.9945 is the angle for the phase. I am also trying to get
v1(t)= 10cos(377t)
for a few periods

omega = 377;
t = (0:0.01:(6*pi))/omega;
v = 5.6576*cos(omega*t+44.9945)
v1 = 10*cos(omega*t)
figure
h = plot(t,v,t,v1)
legend(h,{'v','v1'})
