a 32sii equation bug? Message #1 Posted by Les Wright on 17 Mar 2007, 8:23 a.m.
A recent thread dealt with integrating the bell curve integrand, exp(x^2), on the HP48G, and I have been playing with the problem on my recently acquired 32sii.
When trying to integrate this expression as an equation, the calculator does not seem to like exp(x^2) in that very form and never seems to converge. But it seems to like exp((x^2)), 1/exp(x^2), and exp(sq(x)) just fine. It also works adequately when the function is provided as an RPN program (RCL X, x^2, +/, e^x).
The 33S handles exp(x^2) just fine in that form, without any need for extra parentheses or alternate representations of the quantity to be antilogged.
Weird....
