Hi Valentin,

Thanks for this nice New Year present !

I was inspired by your 2nd problem:

I had no special problem to evaluate it on the HP-71 (actually Emu71:-) with the Math ROM, after a simple operation.

Using your great "Identifying Constants" program, I found the symbolic value, a nice surprise, that lead me to another conclusion about the expression to integrate :-)

Thanks again,

J-F
