Casio FX9750GII Graphic Calculator - Answered Questions & Fixed issues
Where is the less than sign?
The relational operators (=, >, <, and similar symbols) are available in two places. If you are trying to draw an inequality graphPress the Graph Menu, Press F3:TypePress F6:> to access other tabs. The 4 inequality symbols are availabe in the following screen.Press F1:>, F2:< etc. to type in the inequality sign in your inequality.If you want the relational operators for some other purpose, you can access then in the catalog of commands.Press MenuPress 1:Run>Mat to go to the main calculator screenPress [SHIFT][4] (Catalog] to open the Catalog.Scroll up or down until you reach the relational operator you want.Select it and press EXE.

Not found message when trying to get the minium on the graph
Either you have an idea where the extremum (minimum/ maximum) might be (its x-value and maybe its y-value) and you set the center of the graph accordingly, or you zoom out until you locate it.Them you change the center of the graph to be about the position of the extremum. There is no ready made recipe that will work for any function. Just Trial and error. It might help calculating a few values of the function for x=0, x=-10. If the extremum happens to be within the table that the calculator generated to draw the graph, then it will be found.
How to write long programs after using all alpha keys memory with casio fx 9750Gii
I believe you must rethink the design of your program
If you have several inputs that lead to a single result you want to keep for further calculations, enter the inputs, calculate your result and store in a variable. The intermediate variables can be set to zero (by precaution) and reused.
Use functions, and subroutines. Usually, in well designed programs, the scope of a variable defined inside a function or subroutine is local :It can't collide with the same name used globally (global scope). If a variable is no longer needed destroy it and reuse it..
Can the FX9750GII derivate? please answer quickly tanks
Can it differentiate functions? Yes it can. More specifically, it can evaluate the 1st and 2nd derivatives of a given function at a given point (Numerical differentiation).
On any graphed function you can configure the calculator to display the first derivative. When tracing the curve, the 1st derivative is also shown at the trace point.
For any function, not graphed

Hi Danny,
is it correct battery.
please check if it is good.
leave it a half an hour wit case opening or heat it with 10-20 secs with hair dryer and try again with good battery,

How can you take any root above the 3rd on this
You can use the SHIFTED [^] key (Xroot) . Enter the index of the root (4, 5, 6, nth), press [SHIFT][^] then the radicand.You can also use the fact that nth-root is equivalent to a power (1/n)
