Plotting cos functions in matlab

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

Answer 1

[the cyclist]

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'})

thank you!

[Rajvir Dargan]

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'})
