CASIO fx-991EX vs fx-JP900 - lrdheat - 12-20-2017 03:44 PM
Interesting note for folks (like me) that order the Japanese version of the CASIO CLASSWIZ fx-991EX. The Japanese version, with more functions is the fx-JP900.
The U.S. Version accepts d/dx and integrals in the solve capabilities. This, of course, is useful in finding min or max of a function when d/dx is set to zero. I just discovered, to my surprise, that d/dx will not work on the Japanese model!
