Incorrect Simplify - chazzs - 10-02-2015 08:23 PM
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, CHUCK RE: Incorrect Simplify - Tim Wessman - 10-02-2015 08:39 PM
It does. The issue is with the parsing of the copied text into the 2d mode. Specifically, the sqrt(1/4) turns into sqrt(1)/4. To be clear, pressing the "simplify" button works fine. It is exclusively the copy/paste part that has an issue. What appears to be happening is the sqrt -> √ replacement is incorrectly identifying that parenthesis are not required. Definitely now on the list for correction. Many thanks! |
