Introducing LaTeX Math Typesetting

[Tom McCurdy]

$$ax^n$$ hello just testing

 

[robphy]

Can you tell me how I can create a dvi file with images/pictures included ?
Thanks

In LaTeX, you can use \includegraphics
see http://www-group.slac.stanford.edu/techpubs/help/figures/latex2efigs.html
and http://www.linmpi.mpg.de/~daly/latex/grf.htm

 

[h8ter]

test again...
$$\sqrt[3]{27}=3$$

james11,

Try it without the spaces.

$$x_1 *<br /> x_2<br /> x_3$$

 

[Emc2brain]

[ tex ] a^x_n [ /tex ]

 

[Emc2brain]

$$a^x_n[/tex ]<br /> <br /> trial 2 (w/o spaces)$$

 

[Emc2brain]

Eke! Oh Well..i'll Try This Later

 

[chroot]

Emc2brain,

You still have a space in your trial 2.

[humanino]

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

 

[cyber ghega]

$$A=x^_n$$
but
$$f(t)=alpha_n$$

[james11]

$$a^x_n$$

Trying without the spaces!

 

[james11]

test

$$P=2pieG/3*P^2*R^2$$

 

[james11]

test!

P= \frac{2 \p G}{3}p^2r^2

 

[james11]

Lets try again!

$$P= \frac{2 \p G}{3}p^2r^2[\tex]$$

 

[james11]

Lets try again!

$$P= \frac{2 \p G}{3}p^2r^2$$

 

[james11]

just testing!

$$<br /> P= \frac{2 {\p} G}{3}p^2r^2$$

 

[james11]

$$P= \frac{2\pG}{3}p^2r^2$$

 

[james11]

$$P= \frac{2{\pG}}{3}p^2r^2$$

 

[james11]

$$P= \frac{2{\p[G]}}{3}p^2r^2$$

$$P= \frac{2{\p[G]}}{3}p^2r^2$$

 

[james11]

$$P= \frac{2{\p}{G}{3}p^2r^2$$

 

[james11]

$$P= \frac{2\pieG}{3}p^2r^2$$

 

[james11]

$$P= \frac{\2pieG}{3}p^2r^2$$

$$2\pieG}{$$

$$\2pieG$$

james11,

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

Testing...

The quick brown fox jumped over the lazy dog who could not get images to upload properly.

Testing...

$$\Vec{v}(x,y,z)=\frac{1}{x^2+y^2+z^2}(x\Vec{i}+y\Vec{j}+z\Vec{k})$$

$$\frac{\partial v_x}{\partial x} =-\frac{2x^2}{(x^2+y^2+z^2)^2}+\frac{1}{x^2+y^2+z^2}= \frac{-2x^2}{r^4} + \frac{1}{r^2}$$


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.
