Please look at the picture:  A function defined with "if" can not be integreated. "int" does not like "if"  . Could they like each other?  Regards, Radovan |

As Greg pointed out, something is wrong. It seems that the direct calculation of the expression which includes relational operation will be OK. I tried it directly and the transformed form as well (yellow tooltip). Plotting and calling the defined function containing relational operators will go wrong sometimes (plotting, calling or both). I can not see the pattern. Here is another text example.  Regards, Radovan Edited by user 18 October 2009 13:44:44(UTC)

It seems I was wrong. Here is the example where the summation with relational operation fails:  Additionally: x←10sum((k^2*(k≤x));k;0;10)=1Regards, Radovan Edited by user 17 October 2009 21:16:53(UTC)
