# How to Graph using a Computer?

umm guys, i really need your help on this one. I had this math subejct before wherein i used the book, if i remember correctly, The Calculus 7 (TC7) by Louis Leithold. I saw some graphings in this book, also some where there were this graphs of functions revolved either along the x or y axis. I understand that this refers to volume produced by revolving then being solved by integration.

What i want to know guys is how do you do such graphing in the computer, such like graphing a parabola and revolving it along the x-axis. I looked at the preface of the book and said it used mathematica and adobe illustrator, but i can't seem to be able to do it, since im a newbie.

Anyway, can anyone of you recomemd a program or it can be a link to a tutorial to accomplish this? Thanks. :)

Do you own a copy of Mathematica?

Graphmatica is a free downloadable program that allows you to create any kind of graph, however, it doesn't have the feature of rotating the graph around a certain axis.

But it's still better than having nothing ^_^

i do own a copy of mathematica version 5 and also adobe illustrator 10. so anyone who can give me a tutorial to acomplish graphing a function then rotating it to a certain axis to generate a solid of revolution?

please, i really need to learn how to do it. i'm pretty much curious. :)

Hi ermines,

From Mathematica's website:

Shows how to do all kinds of plots with examples.

If you need more explanation than that, just ask.

thanks enigma although i think i saw that one already at the help file included in the mathematica cd. what i really want to know it it really is possible to rotate a certain function with given bounds on a certain axis to generate a solid of revolution using mathematica. i'm actually using illustrator now with its blend tool to accomplish this task but i still don't have any luck.

well, im still waiting for someone who could give me a tutorial. thanks :)

You can try Gnuplot, it is the one mostly used by most people who publish in respected journals.

Use TI calculator and just connect to the computer
