I have a student who has a Casio calculator that will not evaluate some of the
integrals that the TI83/84 will evaluate easily.  One of the integrals in
question was Int from 0 to 1 of sqr root (1 + 16/(81x^2/3)) another was 2pi int
0 to 4 of x sqr root (1 +1/(4x)).
I have asked the student bring in the manual for his calculator so we can find
our why it says mathematical error. I don't know what model his Casio is and am
not as familar with its operating system.
