I installed the OS update for fx-9860G(slim) when my calculator was actually just the fx-9860G (NOT SLIM). this caused my screen display to turn upside down and the functions of my calculator's buttons to be entirely messed up. anyone knows how to solve this??

I am sorry to disappoint you but the Casio FX-986G does not handle the calculations of the eigenvalues and eigenvectors of matrices. Maybe the newer OS versions can do that.

The Graph 100+ sold in Europe (I forgot the equivalent model in North America, maybe the FX9860GII Plus) can find eigenvalues and eigenvectors. Here is how it does it. See screen capture below. Compare with your calculator to see if you have the EigVl( and EigVc( commands in the catalog.

Unfortunately, the Casio FX-9860 G does not have a Computer Algebra System or CAS. For this reason it can only calculate definte integral over a given interval. The lower and upper limits must be supplied. The result will be a number.

Casio calculators that have a CAS are the Casio ClassPad CP330/ 300Plus/ 330, or the Algebra FX 2.0.

There is a program called Prime Factor Analysis on this site. It is written for the FX-9750GPlus calculator but I suspect you should be able to use it on the FX-9860G. To access the site you must have an account. You can register and it is free.

-15x^4 / 3x = -5x³ for x 0.

You should be able to figure this out without having to resort to a calculator. Note the "for x 0"... the two functions are identical everywhere, except the -15x^4 / 3x version is undefined for x = 0 (3 times 0 is 0 and you cannot divide by 0). The function has a "hole" at this point. -5x³ does not suffer from this defect, for x=0 it simply evaluates to 0, so you have to mention this fact to make it proper.
