Question

How do I integrate this function?

Answer 1

I don't understand how the integral of this function becomes \[\int\limits_{-T/2}^{T/2} A e^{-j2\pi ft} dt = AT(\frac{ \sin(\pi fT) }{ \pi fT }\]

Answer 2

I got up to \[A/2 (\frac {e^{-j2\pi f (T/2) }} {-j2 \pi f (T/2)} - \frac {e^{-j2\pi f (-T/2) }} {-j2 \pi f (-T/2)} )\]

Answer 3

ignore the 2 under the A that was a typ

Answer 4

typo

Answer 5

sinx = (e^(jx) - e^(-jx)) / (2jx)

Answer 6

helps ?

Answer 7

oh cool yeah it does thanks!

Answer 8

:)

Answer 9

oh except why is it sin(pi f T) and not sin(pi f (T/2))?
