Quiz: calculating a definite integral

[peacecalc]

Hello Thomas,

If I use fix 4 on the hp 15c (the very old version no LE) I get in some seconds a correct result (like N=20, some posts above), that shows the algorithem functions well.

Maybe the problems by fix 9 are caused by calculating the integrand: instead of \[ x^{-x} \] as \[ \exp(-x\cdot\ln(x)) \]. That have a great alteration rate near zero. The hp 15c algorithem don't calculate at the limits the value of the integrand, but for getting a higher precision it runs into a great number of calculations.

Sincerely

P.S. I have to correct myself, even with 0.01 or 0.1 it doesn't come to an end.
