Calculus approximate integral fails

jsmeyer's picture

I am using windows 7 and SWP6.06 and am trying to use the Calculus Approximate Integral sequence. However, using the same techniques as in SWP5.5 (where the function works nicely), SWP6.0.6 tells me "the approximate integral is null". Again, I don't know if I am doing something wrong or if there is a bug in this version.
SOS.
