Do you want a calculator application that can do numerical integration 
of a function like a HP hand held calculator?

I suggest that you will probably need a scientific plotting program such 
as GNU-Plot.  I don't know what methods it uses or how accurate it is.

I thought that there was a KDE front end for GNU-Plot, but I can't find 
it.  All I can find is a Qt front end:
