Mathstud28, it a really good work! I find it fantastic how you evaluate integrals (Bow)

(just a small note: the inverse functions of the hyperbolic functions are the area-functions, not arcus functions (as you know of course), which the abbr. name is arsinh, arcosh, artanh, arcoth, arsech, arcsch of - all I mean is, it's not arc... but ar... ;))

Inverse hyperbolic function - Wikipedia, the free encyclopedia
I pretty much like the notaions arc and ar instead of that one with ^-1 cuz the 2nd one is ambiguous - you can think of it as 1/function
