What’s wrong?

what am i doing wrong? plot not showing up. the t&v is in parenthesis

[Kevin Barkett]

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?
