    Great job explaining this example! Exactly what I was looking for. :)

    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.

    thank you for explaining this question .. your explain is very simple :)

  • @DanielGonzalez-sw1kf
    @DanielGonzalez-sw1kf Před 7 lety +31

    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! :)

  • @talsokolinsky6611
    @talsokolinsky6611 Před 6 lety +1

    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?
