Hi i want to buy a calculator . What model is the best? Is there anyone that supports a big variety of electrical and computer engineering programs? I was thinking about fx-9860gii SD (because of nyquist , bode etc), is it a good choice ? I ve seen the files at file sharing systems, can i find more programs at another site?


thanks in advance

I would recommend the fx9860. ;)

thanks in advance


i'm a electrical engineer.
when i was in the university in 2007; i bought a casio fx-9860g
but in that year when i search the Google for the electrical engineering program for the fx-9860g;
i found nothing !!!!!! on that year i had a dream("can i write by myself !?")
that dream come true now.
if i want buy a calculator now; my choice is TI89
if money is not your problem TI89 is the best choice for electrical engineer field
see below applications for TI89:
http://www.ticalc.or.../basic/science/

but remember work with TI89 at the first use is complex;but after 2 or 3 weeks you can work with
that. TI89 have CAS(Computer Algebra System) too

if you want CAS(Computer Algebra System) 2nd choice is Classpad(i see a lua program that plot bode;gain and phase margins;RootP;Residue;StepUnit for Classpad in the file sharing)
see:
http://www.casiocalc...pad.Lua#totitle

some functions of Classpad related to electrical engineer field:
solve ==> find real or complex roots of polynomial up to n'th power
taylor ==> finds a taylor polynomial for an expression with respect to a specific variable
laplace,invlaplace ==> find laplace & inverse laplace transform
fourier,invfourier ==> find fourier & inverse fourier transform
FFT,IFFT ==> find fast fourier transform & inverse fast fourier transform
LU ==> return the LU decomposition of square matrix
eigVl, eigVc ==> find eigenvalue and eigenvector of square matrix
rank ==> find rank of matrix

but i hate classpad(why?) because i hate touch screen

if you do'nt want pay more money(and do'nt want original CAS); the fx-9860g|| sd is 3rd choice
it have:
1-two non original CAS produced for fx-9860g see:
http://cas.jeuxcasio.com/en/
http://www.casiocalc...?showtopic=3632

2-find real or complex roots of polynomial up to 6th power
you can download LAGUERRE.G1M to find n'th roots(i test that and works fine)
see: http://www.casiocalc...1-0?load_that=1

3-i write some programs for calculate LU decomposition and rank of matrix
4-i write some programs like: root-locus bode nyquist Routh-Hurwitz
5-i will shared nichols in the next 2 days
6-i will working on the margin that find gain margin and phase margin
all above programs works fine like MATLAB and i use those everyday to solve
exercises of below book:
"Modern Control engineering by Ougata Katsuhico"

well when i bought my casio fx-9860g; i was disappointed
but now i'm satisfied
