    Casio Algebra Fx 2.0

Posted 29 December 2019 - 08:16 PM

Hey everyone,

 

first time poster, hope it's in the right category.

I've a got a Casio Algebra FX 2.0 (pretty old, i know :D ) and i wanted to explore the programming menu a bit. I wanted to write some simple code that would find calculate the derivative of a function (input by the user) and then find where that derivative is 0.

 

This is what i wrote that i thought would get me my result (it resembles the steps i would use to get the result in the CAS menu):

 

? -> A

d/dx(A) -> B

B=0

solve(B,X)

 

If I input X²+2X+1, it results in 5.19 for example.

 

This is not at all what i'm looking for. Through some digging and trial and error i've realized that every equation i enter into the program doesn't actually use x as a variable as in the CAS menu but as in the Run-Mat menu. Is the Algebra FX2.0 not able to do what i want or do i need to use some special commands and syntax to get me my results?

 

I hope i've explained my issue so that people can understand what i mean :D

CAS mode is actually an add-on application (like apps in 9860Gii) and your programs run, of course, outside of this application.
