Hi there,
It looks like the parenthesis of the variable 't' should not encapsulate that first colon, and also the arguments for the plot command should be contained within parenthesis. Try:
t = 0:(1/6000):(1/30);
v = (4*cos((120*pi*t)+(pi/3)));
plot(t,v);
Cheers, Kevin

Is this what you want ? Works fine.
t = 0:1/6000:1/30
v = (4*cos((120*pi*t) + (pi/3)))
plot(t,v)

The code in the answer should not result in an image like you posted. What exact code did you use?
