Can some one tell me how to do this?

Question

Draw graphs in their time and frequency domains.
Time domain
h(t)=5Cos(2pi(6)t)

Frequency domains
h(f)=5/2(sigma)(f-6pi)+5/2(sigma)(f+6pi)

Answer 1

I would use Excel ..

Lets do it by rows.

Row 1 = 't' (fill it in with ascending numbers i.e. 1,2,3,4,5,6,7,8,9 ....)

Row 2 = formula 5 * cosine (2 * PI * 6 * T) where T = number from row above (& PI = a constant)

Then use the Graph wizard.

(same with second case .. first Row = F = 1,2,3,4,5,6,7,8 ... second row = formula)

Could you plot it then write down an expression for the x values (>

OK Stevie Baby. I, like may other Martians, are really upset with Excel.
It takes away our glory, and destroys our plot to take over the world.
