Re: Evaluate this integral
Of course not. Do you honestly think they even read those? I have emailed them many times with no affect.
Ever heard of Bondarenko?

Assuming Doron refers to Doron Zeilberger, wouldn't that be good?

Re: Evaluate this integral
He is hated by the math community. Ridiculed and denied tenure by lesser mathematicians.
Each one is stating there are skeletons in the closet. When people ask about them they are ridiculed.
Bondarenko who I got to know on another forum has been compiling a list of errors that packages make. It is miles long. It has caused him to be ridiculed and barred from forums.

Re: Evaluate this integral
-(1/2)*(x^4+1)^(3/2)/x^2+(1/2)*x^2*sqrt(x^4+1)+(1/2)*arcsinh(x^2)
This is maple 11's answer to the integral of [(x^4 + 1)^(1/2)]/x^3 (after a little simplification of the
integrand).
Looks like a combo of (x^4 + 1)'s 3/2 power divided by x^2, 1/2 power times x^2 and an arcsinh(x^2). So it is probably amenable to various substitution techniques but probably several of them. Could be quite tricky!

Hi;

I think he is a combination of all three.

Who is M? Isn't that James Bond's boss? Seriously, is M for Maple or for Maxima or for Mathematica or what?

Re: Evaluate this integral
I enjoyed looking at your answer Bobbym, but I don't understand how you got
from
I'm not certain if this answer is correct, but it's the same answer from Mathematica.

Re: Evaluate this integral
Hi Fruityloop;
That is because there is supposed to be a du in the numerator. Fixed the original post. Tried something new with the latexing and it just did not work.
