This double integral will make you love calculus

Some multivariable calculus today with this lovely double integral with full solution development using some symmetry of the integrand and some nice tricks here and there.

Since "f(x)" is already taken, the best name for a mathematical rock band would be "+C" (or "Plus C"), so no one who listens to them forgets to add it ever again!

The name for your hypothetical rock band follows from the result: Two Log Two.

In finance, ln(2) is also known as Rule of 69, Rule of 70, or Rule of 72 to mentally compute the doubling time of your investment by the expected return. For example 7% return will approximately double your investment in 10 years, i.e. (1+0.07)^10 ~ 2.

Very interesting Integral and smart solution. Thank you.

I2 is pure joy, by parts trick (v=x+1) is lovely. 14:14, 1 +x not x^2 in the denom, , so many typos lately 🙄

Me used xy = (1+x)(1+y) - (x+y) - 1

As an Irishman I have the right to sue you for that accent. Still better than Tom Cruise.

You are too much obsessed with integrals.

[@polyhistorphilomath]

In the spirit of "Simon & Garfunkel", how about "Euler & Gauß"? "Lenny & Carl" sounds like a Simpsons reference, but The Simpsons is not worthy.

Please, for the love of all that's holy, _never_ attempt that accent again.
