Use the linspace function to plot the following:

a. v(t) =120sin(wt) 
b. s(t)=10rad(abs(sin)(wt))

where W=2pi*60 is the frequency of the electric voltage in USA, and t=E[0 to 500] sec.

This is obviously homework. If you post some code showing that you tried, someone might be willing to help you.

The problem is I don't know where to start, my teacher is horrible and I can't find any info online.

2*Pi*60 is not the frequency of AC voltage in the USA: the frequency is 60 Hz.

What is E[0 to 500] intended to convey?
