Cool examples robphy!

[wisky40]

this is wisky40 I'm not sure about this, but I'm going to try to write something using
Latex...$$E=K\lambda\int_{-a}^a \frac{dx_1}{x_1+x_2+b}$$

 

[ExtravagantDreams]

How do I make this look better

$$a_0 (t)$$

where a₀ is supposed to be a function of t and not a₀ times t.

 

[chroot]

ExtravagentDreams,

It looks fine to me as it is... what do you think is wrong with it?

- Warren

 

[ExtravagantDreams]

$$a_0 (t) \partial a_0 = t^2 \partial t$$
I don't know. I just think it could sometimes be difficult to read and understand if it is ment to be a multiplication or a function of this variable.

I wonder if it would be better to use these {}


such as
$$F_g \{s,t\} = ...$$

Does that conflict with anything else? I don't think I have used any sets in this manner, then again there is much math I have still to see. But I think it would be a little more obvious that it isn't a set instead of it not being multiplication

$$F_g^{ \{s,t\} } = ...$$

$$F_g^{ (s,t) } = ...$$

$$F_g (s,t) = ...$$

$$F_g \{s\} = ...$$

$$F_g (s) = ...$$

try a font size change


$$F_g \mbox{\Large (s,t)}$$

$$F_g \mbox{\large (s,t)}$$

$$F_g^{\mbox{\HUGE (s,t) }} = ...$$

 

[chroot]

The parentheses are standard notation...

$a_0 (t)$ is a function, $a_0 t$ is a multiplication.

- Warren

 

[ExtravagantDreams]

I suppose that is a good point. Now I am having trouble getting the font size to work though

 

[chroot]

$$\mbox{\Huge a_0 t}$$

$$\mbox{\LARGE a_0 t}$$

$$\mbox{\Large a_0 t}$$

$$\mbox{\large a_0 t}$$

- Warren

 

[plover]

All four of those a₀t's are formatted to the same size on my screen.

EDIT: The sizes are fixed now.

If you overload your post with too much latex math writing? Will it come out as errors?

Since, I think I may be doing so. As I was trying to verify in my post how I implicitly differentiated this equation, I used a lot of Latex Math writing to show my work. Then I preview it and it comes out with unsuccessful results.

EDIT MESSAGE: Nevermind, I found a couple of errors in my latex math writing. I fixed them and it came out great.

$$v = A\sin(\omega t + \epsilon + \phi) <br /> + \sum$$

$$k = \sqrt{\omega\kappa}$$

 

[Gonzolo]

This is just a test.

Hello everybody!
Do you know how to write in Latex a big square cap with underlying text like formulas in display math style?

Just trying to figure out if there's anything in particular screwing things up:

This is a test of the new latex hierarchy:

$$\vec v \cdot \vec u = 100$$

[chroot]

This is a test of the new latex hierarchy:

$$\vec v \cdot \vec u = 20$$

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