Can somebody check this for me. I don't have the latest software on my work calculator.

Integrate sqrt(1/x-1) from 1/2 to 1 with the minimum or none simplification set in CAS settings.

It returns correctly 1/4*pi - sqrt(1/4).

However, upon simplifying (or copy and pasting) it will convert the sqrt(1/4) to sqrt(1)/4, obviously quite wrong!!

Setting the simplifying to maximum gives (pi-2)/4 which is correct.

However the incorrect simplifying is troubling. Does this also occur with the latest firmware?

Thanks,
