Below are some of the apps, which would help teachers and students -

sagemath - it's the best among computer algebra systems available for free. I guess only mathematica provides more functions than this, which isn't free.

But I love sage, it's simply great! You can find ebooks teaching you calculus with sage, and documents exploring other areas of math as well.

geogebra - a cool application for exploring and knowing about geometry!

K3Dsurf - An extremely fast 3D surface generator. The fastest I've seen yet.

If you use any other apps, please let us know

Hi gAr;

Welcome to the forum.

Geogebra is great. Solves problems in an intuitive geometric way. Sketchpad is slightly superior. Compass and Ruler is also good.

Sage, what can I say about it. They have not ported it to windows yet. They have been dragging their butts in this and it is killing their app. Their solution, run a virtual windows operating system. Hate to say it boys, but Windows is the standard.

Mupad lite and Maxima are good alternatives.

Hi bobbym,

thanks for mentioning the apps...

ya, windows is the standard, though it's sub-standard . I too used it as a beginner. The main reason I can think of is that the vendors pre-install windows in most of the systems. I was so used to ctrl+alt+del!

Agreed, but software developers must realize that windows is on 90 percent of the machines on earth. If you want your product to fly you have provide for windows people too.

I too used it as a beginner.

Neither is the correct use of Windows for beginners.

Incidentally, I use Ubuntu and puppy also but my version of Windows is not for beginners. If you know your stuff things can be done to Windows to make it competitive to any linux and you have more software.

It is a sad fact that software vendors are either compliant or owned by the boys in Redmond. I would have loved to have seen Linux wipe Windoze off the face of the earth. I have been following linux for 12 years and they still only have a small piece of the market. They are never going to over throw Windoze. A wise man knows the world he lives in and that world is Windoze.

So what I do is keep abreast of Linux just in case and fixed XP. You can hybridize it. High speed, small signature, no backdoors. My OS is half the size of Ubuntu with more apps. Then again I am old assembly language programmer not too many of them left.

yes bobbym, i agree... but I believe no one can really keep track of the no. of linux systems used. Download counts won't give the counts of the systems, since in many cases it's installed in multiple systems and shared offline among users.

sage windows port may be availble in the future - http://windows.sagemath.org/

for now, a windows installer has been created. It's mentioned "Technically it is similar to a WUBI install, but automated"... But I haven't tested it -

http://groups.google.com/group/sage-edu/browse_thread/thread/10d4bbf40c6f39ca?fwc=1

and do you still write assembly codes? Which assembler are you most comfortable with? I find fasm to be good...

writing asm codes is really the way to learn computers!

Hi gAr;

Not anymore, nothing other than mathematical programming, for that I use higher level languages. I used to use masm and nasm. I found that I did not like the 80386 architecture, I preferred the MC68000 family. Since I never owned a Mac I never got the chance to really do much. I liked reverse engineering the best and found it to be the most useful.

I follow the sage page. I also follow the ReactOS effort.

ok bobbym, nice to know you

keep up the good job of helping people with their math...

CaRmetal is another interactive geometry software. It looks neat. It can even plot implicit fuctions.

Check it out: http://db-maths.nuxit.net/CaRMetal/index_en.html

Hi gAr;

I have used CAR, metal and the other normal one. It is a pretty good program but I think Geogebra is slightly ahead of it.

Hi bobbym,

I haven't used the softwares in depth. Hence I can't tell which has better features!

Can I plot trigonometric functions in any of them?

Hi;

Sure can. Type in sin(x) in the input bar on the bottom. Make sure you have algebra view on. Now get the hand cursor and drag it up and down and watch the equation change!

Hi,

I observe that carmetal is better at plotting implicit equations...

But figure does not scale well, the sine curve looks like a line, unless I multiply it by a constant and zoom out.

Anyway, I really appreciate both geogebra and CaR. I find Geogebra easier to use.

Hi,

K3Dsurf is a nice application to visualize 3, 4, 5 or 6 dimension surfaces.

Hi gAr;

I remember that one! Excellent graphics and very fast.

Hi bobbym,

I started playing with that yesterday.

It generates the surface so fast that I feel like it's displaying from a file! Excellent graphics like you said.

But I could not find a way to display multiple surfaces in one screen.

Hi;

I have been looking around to see if there is some tutorial on how to do that. I have been unable to find one yet.
