Integration problem
In Progress
Hi, the following double integral is returning the wrong answer. I've double checked and am very confused by the answer that geogebra returns. The correct answer should be +0.5 more.
ln(1x+sqrt((1)/(4)+(1x)^(2)))

Please post your file, and tell us more about which version of ggb you are using (Classic, Suite...) version number and your OS.
Sorry, in my haste I made a mistake. The double integral is
Integral(Integral(sqrt(1+4y^2),y,1x,1),x,0,1)
I have tried it using the online web version of CAS and I got the answer ~ 0.3484
But using the offline version 6.0.609.0 of CAS geogebra (Windows 10), the answer is ~ 0.8484
Correct answer seems to be 0.8484...
Thanks, we'll check
