Today, I read some function book.

And I drew a lot of graph, but due to the size and my hand-drawing, the output is very ugly.

I want to have a very good graph drawing software.

Can you suggest some to me which are free, simple?

i am building one... but it does not do the 3D functions pretty well....

if you are really intrested send me a private message, to finish it.

If you're using linux, gnuplot is pretty good.

You are very great!

Does the software support function(x)?

I'd want to use a software to draw some graph consist of [MATH] f(x)=cosx[/MATH].

Anyway, thank you for telling me.

I find Graphmatica good for plotting 2D functions.

 

The input [instead of f(x) = ...] is y = ...

 

It's very self-explanatory. Just read the readme.

What are you building it with?

can't use the f(x)=cosx

What's wrong?

How touse the degree sign?

Just use y = cos(x)

 

Degree sign? As in exponents?

 

x⁶ would be x^6

how much better is this software than a TI83+ ?

Are you referring to Graphmatica?

 

Well, the TI83+ is fairly portable, whereas Graphmatica requires some piece of hardware to run it.

 

As far as features go, they're pretty much the same afaik.

so, i should just stick wit my TI83+ ? I am thinking about going to Wal-mart and trading it for a TI83+ silver eddition.

I don't know about you , but when I did calculus I did a lot of curve tracing (drawing graphs) and that too for loads of weird functions, For eg, stuff with loops in the graphs and all sorts of weird logarithmic functions. I personally feel that it helps a lot in learning and definately in problem solving, plus you always have books to check simple graphs like [MATH]f(x)=\cos(x)[/MATH]

Macromedia Flash (actionscript)

 

Well it makes some functions but, i am doing it isometric, thats why i am taking a little bit longer... the real trick is that i am building a renderer more than a graphing tool.

 

When i get back to school (there in Morelos) i´ll upload it.... its a .swf no big deal.

 

andthat GNUplot is quite nice.

there is a winplot it is nice either.

ya f(x)

Should be changed as y.

Flash MX support drawing functional graph?

hey, but why don't we need to enter the degree sign ?

Calculator need to change to DEG first when calculate sin cos

How to extract the graph into gif or bit?

Print Screen, or if you're using Graphmatica: Edit --> Copy Graphs BMP or Copy Graphs EMF.

 

Calculators don't need to change to DEG for the sin(x) & cos(x) functions. RADians or GRADians are fine.

how about a software to plot graph for biology project?

Beautiful one!

Here are some, but they are pretty old:

 

1.Omnigraph: This is the one I am SURE that you could get. I am not sure whether you could plot 3d functions on this.

 

2.Derive, by Smile Software: this is the one my school uses. Again, you can't plot 3d functions on this!

Yes it support graphic, some sort. thought the engine is done by me.

In main windown in the development panel you would see mostly a blank screen and a few buttons.
