Solving Integral Equations

[peacecalc]

Hello Eddie,

thank you very much for your little program.

I added a loop counter for stopping the program after 100 integrations.
For controlling I added some PRINT() commands (and I was astohnished about how fast the the precision is reached).

And I used a another technique for integrating (with cas command "int") and instead of always integrating from the lower (fixed) value to the new upper value, the integration is cutted in parts and added up:

\[ \displaystyle\int_{xo}^{xn} F1(X) dX = \int_{xo}^{x1} F1(X) dX + \int_{x1}^{x2} F1(X) dX
+ ... + \int_{xn-1}^{xn} F1(X) dX
\]

With the hope, if xn-1 and xn converge, the numerical part of integration becomes faster and faster.
