Primarygun Posted July 28, 2004 Posted July 28, 2004 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?
AtomicMX Posted July 28, 2004 Posted July 28, 2004 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.

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.
NSX Posted July 28, 2004 Posted July 28, 2004 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.

Primarygun Posted July 28, 2004 Author Posted July 28, 2004 can't use the f(x)=cosx What's wrong? How touse the degree sign?
NSX Posted July 28, 2004 Posted July 28, 2004 can't use the f(x)=cosxWhat's wrong? How touse the degree sign? Just use y = cos(x) Degree sign? As in exponents? x6 would be x^6
NSX Posted July 28, 2004 Posted July 28, 2004 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.
ydoaPs Posted July 28, 2004 Posted July 28, 2004 so, i should just stick wit my TI83+ ? I am thinking about going to Wal-mart and trading it for a TI83+ silver eddition.
pulkit Posted July 28, 2004 Posted July 28, 2004 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. 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]
AtomicMX Posted July 28, 2004 Posted July 28, 2004 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.
Primarygun Posted July 29, 2004 Author Posted July 29, 2004 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
Primarygun Posted July 29, 2004 Author Posted July 29, 2004 How to extract the graph into gif or bit?
NSX Posted July 29, 2004 Posted July 29, 2004 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.
Primarygun Posted July 29, 2004 Author Posted July 29, 2004 how about a software to plot graph for biology project? Beautiful one!
aommaster Posted July 29, 2004 Posted July 29, 2004 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!
AtomicMX Posted July 30, 2004 Posted July 30, 2004 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.
