RE: CASIO CLASSWIZ fx-991EX
In the solve environment, if one does a d/dx=0 calculation of some equation to find an extremum, one can edit back through the equation, deleting the d/dx which just leaves the equation. "x" that solved d/dx will still be in "x". If you press "=", you will get f(x) at the "x" that represents the extremum.
The integration is not as quick as on the 9860gii. Still, a nice shirt pocket calculator. |
