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). I’ve noticed this too with the infamous ∫(0,2,sin(x)/x) from the 34C/15C manuals. And yes, in this case I needed to replace the endpoint of 0 to a dang near 0 of 1E-10 (or smaller with the range on not only Casio but Sharp, too). |
