    1:39 Can you take the Re operator out of the integral there? Since s is complex, [Re(x^i)]/(1+x^s) can be different than Re[(x^i)/(1+x^s)].

    At 6:05: Is this correct?
    You are creating the complex conjugate of the numerator at the right side from an expression with complex argument s in the cosh function by just flipping i -> -i. For real s this is true, but at that time in the video s could be still complex.

      Don't worry it's perfectly fine. Any adjustments are handled autonomously in the final expression.

    sin^2θcosh^2θ+cos^2θsinh^2θ=(sin^2θcosh^2θ-sin^2θsinh^2θ)+(sin^2θsinh^2θ+cos^2θsinh^2θ)=sin^2θ+sinh^2θ

    What’s the limit of I(s) as s approaches 0 from above? The graph says it’s 0, but the calculation does nothing to simplify.

  • @kappasphere
    @kappasphere 10 месяцев назад

    You're implying at different points of the video that s can be a complex number, but doesn't that mean that you're not allowed to distribute the im() outside the integral anymore at 1:29, because the denominator doesn't have to be a real number?

    • @maths_505
      @maths_505  10 месяцев назад

      Nah perfectly fine. Whatever adjustment from real to imaginary parts are handled autonomously in the final result.

    Hey, in one of your old videos, 1 month ago, you used something named the reflection formula? (It was for the integral of 1/(x⁴ +x³ +x² +x +1) from MIT). I couldn't find a proof without complex analysis or contour integration. Mind explaining how to proof that integral of x^(s-1) over 1+x^n is π/n csc(sπ/n) ?

    • @maths_505
      @maths_505  10 месяцев назад

      Check out the proofs playlist. You'll find a video proving both formulae.

    I discourage drinking but that’s not for religious reasons it’s because I’m a med chemist and ethanol as a drug is awful (as a solvent it’s pretty good though)
