Sell 9860G SD. Buy Algebra fx 2.0 plus.

Since you're talking about Linear Algebra procedures, I asume you know how it's done by hand. In that case download the OS update... It adds the RREF function.
Once you have that function you can go ahead and enter the matrix and do the matrix operations to solve for the eigenvalues, eigenvectors, and the rest of the stuff you want to handle, by following the basics. I know it's kind of a pain in the a$$ BUT it's better than programing the whole thing.
Hope that helps

can you slove (x^3-x^2-8x+12)/(x+3) = ?
ans (x^2-4x+4)
ans (x^2-4x+4)

Im afraid that the CFX series do not come with the capacity to do polynomial division. You must either buy a CAS calculator or download the addin 'Symbolix CAS', which was programmed by kucalc

Yep, Symbolix can do that with ease.
Symbolix v0.45:

You can use the spreadsheet function to find the eigenvalues. This will also give you the characteristic equation.
E F
G H
ax^2 + bx + c:
a = 1
b = -(E+H)
c = ExH - FxG
You do the same for 3x3 Matrix using ax^3 + bx^2 + cx + d:
E F G
H I J
K L M
a = -1
b = E + I + M
c = JL + FH + GK - EI - EM - IM
d = EIM + FJK + GHL - EJL - FHM - GIJ
It will all be automatic in the spreadsheet. Try it out in Excel (I did this very fast, you may have to do your own maths >
Once you have eigenvalues you can ofcourse find the -vectors easily by setting up an extended matrix -> Rref
Hope this helps!

How do you install symboli. I cant get it to work. It is in Rar format, how do you change it into casio format. Please Help. If you can, send me the steps to get it.
