Battle of the Casios

[lrdheat]

…another small con is that CASIO integration often does not deal with undefined endpoints or discontinuities with the domain being integrated while the TI’s and HP’s do better in this regard. Of course, there is a workaround as one can choose endpoints 1e-12 away from an undefined endpoint, one can also break the integral into multiple integrals when discontinuity occurs within the domain…(the 991CW calculates to 1e-22 and endpoints within 1e-17 or 1e-18 of a undefined point can be used).
