Andrew -- very good point! That's not nearly as
It is wrong, but not as wrong as you make it out to be. Your function is f
= abs(h), where h = 2*cos(5/8*sqrt(x)+1/2)/sqrt(x). Rather that integrating
f, it seems to have integrated h.

Hi,
In Sage, this gives a totally wrong answer:
sage: f(x) = sqrt(2+sqrt(2+sqrt(2+2*cos(5*sqrt(x)+4*x^(-1/2)
sage: integral(f, x)
It takes about 10 seconds, and plotting f.derivative(x) - f makes it
clear the answer is wrong.
I tried sympy, but after several minutes it didn't return a resul
Thanks.

Hello,
There is none and that can be tested with
sage: matrix is Matrix
True
I guess that both are there to make them easier to find...
