Discussion Overview
The discussion centers around the introduction of LaTeX mathematical typesetting on Physics Forums, focusing on its implementation, usage, and examples. Participants explore how to effectively use LaTeX for mathematical expressions and share examples of LaTeX code.
Discussion Character
- Exploratory
- Technical explanation
- Homework-related
Main Points Raised
- Warren introduces LaTeX typesetting, explaining its markup style and how to include LaTeX graphics in posts.
- Some participants share additional examples of LaTeX code, demonstrating various mathematical expressions.
- Warren invites suggestions for LaTeX packages to include, expressing concern about performance impacts from too many packages.
- One participant inquires about using the LaTeX generator for personal web pages, prompting a discussion about server load and intended use.
- Another participant expresses enthusiasm for practicing LaTeX by writing equations related to particle interactions.
- A question arises about formatting subscripts in LaTeX, specifically how to create multi-line subscripts.
- Participants provide tips on learning LaTeX, including quoting existing code to see how it is written and encouraging practice.
- Warren reminds participants that clicking on LaTeX images reveals the source code, which can aid in learning.
Areas of Agreement / Disagreement
Participants generally agree on the usefulness of LaTeX for typesetting mathematics, but there are differing views on its application for personal use outside the forum, with some cautioning against it due to resource concerns.
Contextual Notes
Some participants express uncertainty about specific LaTeX formatting techniques and the potential performance implications of adding more packages to the forum's LaTeX capabilities.

In LaTeX, you can use \includegraphics

Emc2brain,
You still have a space in your trial 2.

That would be great if we could draw Feynman graphs ! Is it too difficult to handle ?

Use \pi to represent \pi, rather than using "pie."

\Vec{v}(x,y,z)=\frac{1}{x^2+y^2+z^2}(x\Vec{i}+y\Vec{j}+z\Vec{k})
\frac{\partial v_x}{\partial x} =-\frac{2x^2}{(x^2+y^2+z^2)^2}+\frac{1}{x^2+y^2+z^2}= \frac{-2x^2}{r^4} + \frac{1}{r^2}
In the same way,
\frac{\partial v_y}{\partial y} =-\frac{2y^2}{r^4}+\frac{1}{r^2}
and
\frac{\partial v_z}{\partial z} =-\frac{2z^2}{r^4}+\frac{1}{r^2}
The divergence is
\mbox{Div}(\Vec{v})=\frac{\partial v_x}{\partial x} +\frac{\partial v_y}{\partial y} +\frac{\partial v_z}{\partial z}=
=\frac{-2x^2-2y^2-2z^2}{r^4}+\frac{3}{r^2}=\frac{-2r^2}{r^4}+\frac{3}{r^2}=\frac{1}{r^2}
It is the function
\Vec{v}(\Vec{r}) = \frac{\Vec{r}}{r^3}
whose divergence is zero everywhere except at the origin.
