highlight and erase formatting and see if it fixes itself.

You will note that I revamped section 1.1. That is the general format I want you to follow (irrespective of the typesetting of the original content).

Re: regarding left and right align

Delmar Larsen <dlarsen@...>
 

I would use a standard HTML table via the editor toolbar instead of using mathjax to render the table.

Re: trouble getting rid of parenthetical references at the end of multiline equations

Seeburger, Paul (Mathematics)
 

​You can use the \begin{align*} and \end{align*} version to align without the equation numbering.

Hi all,

I am having trouble with trouble getting rid of parenthetical references at the end of multiline equations. I am using the \begin{align} and \end{align} format for these multiline equations so I can align them by the equal signs on each line, but I can't get rid of the references and I thought that wasn't supposed to happen as long as I use the \( \) format?? 



Re: trouble getting rid of parenthetical references at the end of multiline equations

try adding \nonumber or \notag to the latex code

Re: autonum & Templates #Formatting #referencing #templates #Equations

Dorte Madsen
 

Hi Bob,

a) The formatting difference is because the automatic numbering uses the format from the title. The first example you use has the (correct) title format "11.2: Ion-Dipole Forces" while the second one has a - instead of a . : "14-4: Integrated Rate Law"
Fix the title and the numbering format will be consistent. 

b) I can only answer this partially: Yes, you need a label because that is how the equation is referenced. So for example: 
\[ E=mc^2 \label{EinsteinEq} \]
To reference this equation you have to use the command \ref like this: See equation \ref{EinsteinEq}

Someone else will have to answer the part about referencing across pages, I don't know. 

c) No, you do not need to add anything

Also note that \displaystye should not be used here, find details on when to use that code here (section "when editing math pages")

Re: display error #mathjax

Hi Diana,
The (%) confuses things, I think. I am not sure what you goal is but try
\[\text{Output Gap (%)} = \frac {Y - Y_P}{Y_P} \times \:100\]
and let me know if that is what you are after 
 


Robert Belford
 

I have some questions dealing with autonum and thought I'd post them to the forum.
(a) Why does the first page below show the Figure format of 11.2.2 , 
https://chem.libretexts.org/Courses/University_of_Arkansas_Little_Rock/Chem_1403%3A_General_Chemistry_2/Chapters/11._Intermolecular_Forces_and_Liquids/11.2%3A_Ion-Dipole_Forces
while this page is formated like 14-2.2
https://chem.libretexts.org/Courses/University_of_Arkansas_Little_Rock/Chem_1403%3A_General_Chemistry_2/Chapters/14%3A_Rates_of_Chemical_Reactions/14-4%3A_Integrated_Rate_Law

That is one page is #-#.# . while the other is #.#.#

(b)  if we want to link to an equation, do we still need \label{}, if the numbers are being autonumbered anyways?  .... So how do you link to an eq?  Especially if the link is from a different chapter?

(c) The  Template:BoxExercise states: "Add text here. For the automatic number to work, you need to add the "AutoNum" template (preferably at the end) to the page.", is this still needed?
Is there a tutorial on the use of the templates?
Cheers,
Bob

display error #mathjax

djychen@...
 

Hello, 

I am having trouble getting an equation to display correctly, and I don't know whether it's a site error or my own mistake in the code. I have attached images of my code and the display below. Thank you!

my code: 
\[\text{Output Gap}(%) = \displaystyle\frac {Y - Y_P}{Y_P} \times \:100\]

view the image for the displayed code.


Respectfully,
Diana

Hi Alexandra,
Try this:

\bordermatrix{ ~ & b & c \cr

Based on what I found online, it should produce a matrix that looks like this.

Delmar Larsen <dlarsen@...>
 

Another typesetting right.

In mathjax/latex, instead of using \bigg for surrounding expressions, it is best to user \left and \right.

For example, use

\[\left[ \theta + \frac{ \pi}{2} \right] \]

instead of

\[\bigg[ \theta + \frac{ \pi}{2} \bigg]\]

This is because \bigg doesn't scale very well to different sizes.

Re: Page Indexing Error #Formatting

Delmar Larsen <dlarsen@...>
 

That is because the page is not rendered correct below. All that white space means your HTML is screwy and thus mathjax does not render properly (even if written correctly) above.
