Numerical integration methods

Hi Nigel, I have not tried the WP 34S program, but graphing the function on the CLASSPAD 400, for x=2, f(x)=~.5326, same on HP 35S. Using x=2, and not using a program, just stepping through the equation manually using the HP 42S with it’s RPN (which I love), I cannot produce anything resembling.5326! I’ve come to the conclusion that I do not understand this function at all!
