Symbolic Integration bug in Mathcad 14
Just a quick one – someone sent me the following Mathcad bug report and so I thought I would share it. No problems with it in Mathematica or Matlab (using the symbolic toolbox). I find symbolic integration bugs interesting – especially if they come from one of the well known commercial packages such as Mathematica, Maple, Matlab or Mathcad. If you ever come across any then please do let me know in the comments.
The correct answer is Pi/8- 1/Pi which evaluates to about 0.074 so you can see from the image below that Mathcad gets the correct numerical result but fails to get the symbolic result.
