I'm just curious which (software)graphing calculator do you use?
I'm learning mathematics right now,calculus.I'm too lazy to plot manually on graph paper.
So do you had any recommendation?

Thanks

Ah yes,I never thought of that but I don't have micro$oft office but anyway I have openoffice.
Well actually,it's been a long time since I use excel or should I say,I never really use excel before.Now try and see what's the functionality are open office cal(equivalent to ms excel).
Hmmmm,thanks ......

I use Matlab for everything, even drawing figures.

But you can probably get 20 licenses of MS Office for the price of one Matlab license - or?

There's always gnuplot, of course, but it doesn't have the tools that people expect of graphing calculators (finding intersection points, and the like).

I use a graphics calculator, far easier to do it on paper & calculator.

For my degree we used some matlab, but mostly maple (http://www.maplesoft.com/) :)

MatCad isn't bad.

For a while there I actually used a relatively simple open source graphing calculator. I can't remember its name at the moment (but it was a Windows one).

There was a nifty little open source one that I remember using once or twice before. It was called graphmonkey or something like that. It was functional and did the trick. Its no Matlab... but I would rather drive a railroad spike through my testicle than use excel...

I started using maxima (http://maxima.sourceforge.net/) a few weeks ago, rather nice.

At school we use matlab and maple. At home we are encouraged to use Octave (http://www.gnu.org/software/octave/) (consider it as a free edition of matlab...) and Maple (we get the license for Maple trough school).

It depends on what I'm doing. I like matlab cause it's so feature rich. If I need to do something simpler I use excel.

For linear algebra stuff I use Matlab at school and Octave at home.

For crunching numbers, etc., I will use either Windows PowerToys Calculator or my classic TI-85.

Seconded. And don't underestimate gnuplot -- it can do what you want, it's just not completely straightforward. To find intersections between two curves, subtract one from the other and solve for the zero point.

As far as straight graphing, it works fine.
