Awesome explanation. I’ve taken up to differential equations but always in the real numbers, but having used the Fourier transform once or twice in a computer and other kinds of transformers like the Hadamard which stays in the real numbers but is related to the Fourier, I can say that learning an introduction to complex integration from you has been easy, thank you!

This was a good problem to watch. Made me realize I needed to refresh on Euler's formula to convert the complex number back to the sine wave function.

Also and for being more concrete, you could say that 6/w * sin2w is equal to 12*(sin(2w)/2w), which is equal to 12 sinc(2w), which is the Cardinal Sinus function. I say it because maybe if it's a signal processing exercise you should end your exercise saying this. Btw good video! :)

I didn't understand the last thing, you said that sin(x) = 1/2j * (e^(j)-e^(-j) but then when you input the value to the formula you haven't add the half, so you got 1/2j instead of 1/4j? Or is it just my misunderstanding?

@martyguild

how come the fourier transform is the integral from -infinity to infinity, but you evaluate the integral from -2 to 2? i assume it is because the function is defined as 0 outside of these BOUNDS (they are not limits, but bounds)... therefore the area under these parts of the curve will be 0, but this is not something that should just be hand-waved away. you also drew a theta and called it delta...
