    How do I interpret negative frequencies? Same as negative amplitudes?

      No, when you take the Fourier transform of a pulse, you will get a frequency spectrum that is symmetric about the w = 0 point and represents the amplitude as a function of the frequency. Typically these pulses contain a carrier frequency which will shift the frequency spectrum to the right and will then be symmetric about the w0 point which will then no longer be zero.

      Mr. Biezen seems to laugh very easily.
      In fact, he has an entire blooper video on his channel that shows all the outtakes, and in some of those scenes he laughs uncontrollably for a _very_ long time, lol.

      I think because he felt silly and took too long to remember what he had to say and after saying it he says "and that is the answer of that".
      I think that's funny

    At 4:57, why it becomes cos? In the previous video, it is Sin. Could you explain it for me? Or could you let me know what the transformation is called?

      sin(x) = (e^jx - e^-jx) / 2j
      cos(x) = (e^jx + e^-jx) / 2
      In this case the sign is +, so it's cos.
