    The Lemniscate constant was news to me. You just gave me food to chew on further... The exploration continues... Thanks for the beautiful solution. I am elated when we get to the Gamma function and its sisters!

    That really was AMAZING. I started to see the Γ(1/4), (I shouted LEMNISCATE) then square root of two, and, then, PI. 😍

    Whenever you see the square of Gamma Function of 1/4 in an integral, usually your answer will be a lot simpler if you express it in terms of either the Lemniscate Constant as you said, or with Gauss's Constant, G, the reciprocal of the arithmetic-geometric mean of one and the square root of two. If you multiply Gauss's Constant by Pi, you get the Lemniscate Constant. Using that constant. the value of the integral is:
    (G * Pi^2 ) / (2 * Sqrt[2] )

    @mathunt1130 11 месяцев назад

    I think that once that the double integral has been reduced to a single integral, and the definition of sinhu=(e^u-e^-u)/2, take out a factor of e^u, and then expand the square root as a power series, and you end up integrating u^n*exp(-ax), and that gives you a nice series as a solution.

    Lmao I've never heard of the beta, gamma, digamma functions, or the lmniscate constant. Still very much enjoyed the ride. Also, that's a psi, not a digamma, am I trippin?

    • @maths_505

      It is psi but it's called digamma function

      I was solving PDE’s… you know… heat equation, waves equations, Laplace equation in any dimention and variation💪, but there is a problem with Poisson equation and Green’s function. I undrestand idea, but on wikipedia, the formula for Poisson equation has is not addicted to boundary and initial conditions… whatsmore i do not understand the notation… This is the last equation i wanted to study, but there is little information abput it…
      Anyway I am very addicted to mathematical analysis as you can see 😂, bu this is just beutiful when you solve all of this problems!!!
