[TI-M] Re: complex matrixs etc.
Hi!

i discovered this way myself :)
and now use it
Thank you for help.
I've got another question about "simple fraction" in algebra,
i have a function like this
1/((x+1)x^2)
and i want to write it as "simple fractions" (in polish we call it
that), so it will come:
1/(x+1) - 1/x + 1/x^2
Does anybody know function that can do it for me?
