As always, thanks for your prompt and detailed help. The solution you provided makes it obvious what I overlooked ... I needed that! Also, thanks for the "otherwise" usage help, it made it much more straightforward. Oh yes, thanks for leaving the clue to the definition case that I overlooked and left out as well.
Looking at it again I still don't understand why the integral from 0 to infinity (we had that in another thread) does not work.
And in this example I don't understand why the first integral (from 0 to 0.1) works, because the integrand is not defined for the range from 0 to 10^-5). Mathcad - always good for a surprise 😉
