Solve & Integrate from the other guys

[lrdheat]

The TI integration methodology handles convergent examples with discontinuities while the CASIO’s often require dividing the integration into 2 integrals or integrating from the offending limit plus/minus 1E-12. The HP 35S can handle discontinuities, but in order to complete the integration in a reasonable time (without breaking into multiple integrals), an epsilon of .01 or .001 helps on many examples. One thing I like on the HP is that a correct fraction is often supplied when asked for when using an epsilon of only 1E-04 or 1E-05. The TI and CASIO will not convert to a fraction if even a hidden digit beyond the 9th decimal shown disagrees with the 12 digit fraction representation.
