Problem with Improper Integration - Is Zero the Correct Answer?

[killerfish]

Hi again,

I have a problem regarding improper integration.

Homework Statement

Refer to the image. I tried to solve and got zero for the answer. Is that correct? I refer to my actual problem it seem like it don't won't this way...

Thanks

suppose that g(t)=1, what is the value of the integral?

suppose that g(t)=1, what is the value of the integral?

If 1 is integrated, we get t and then sub in the boundary value the answer still 0?

here the actual g(t) suppose to be g(t) = cos(2$$\pi$$f₀t) - jsin(2$$\pi$$f₀t).

Are you saying that you are not capable of integrating
$$\int_{-T/2}^{T/2} dt$$
or you just haven't bothered to?

here the actual g(t) suppose to be g(t) = cos(2$$\pi$$f₀t) - jsin(2$$\pi$$f₀t).
