# How do you use the Fx equation editor?

##### SUMMARY:

Electronic Lab Notebook (ELN), provides you with a rich text editor that allows you to use a page with many functions, like the photo, plate, chemistry editor, creating LabCollector links to reagents and supplies, copy-pasting from Word document directly, and many more. it also provides you with the equation editor that you can use for your calculations.

Users involved in computing, maths, statistics, engineering, finance, physics, etc can take advantage of the equations editor function in ELN’s, rich text editor.

Fx can be used in a wide range of circumstances to create beautifully formatted mathematical equations in LaTeX in LabCollector.

To use the Fx equation editor, please follow the below steps:-

1. The Fx equation editor

2. Editing with equations editor

# 1. The Fx equation editor

- To check the default fields for each module go to
**HOME -> BOOK / EXPERIMENT OR PAGE(OF YOUR CHOICE) -> CONTENT -> EDIT**.

- When you click this icon you will an equations editor like below, where you can select the functions and write the equation and preview it at the same time.

# 2. Editing with equations editor

- The equation editor is based on latex. Latex is software for typesetting texts.
- Latex is easy to use as you can construct your formula onscreen with the help of predefined functions, as latex code can be edited manually.
- The equations editor in latex has various functions where you can edit or create formulas as you like.
- Below is a small example of creating equations with equation editor and insert in the ELN content page.

- The equations are inserted as an image inside the ELN content.
- If you want to edit the equation again just click again of the Fx icon and your equation will be already present in the latex code.

**WARNING**

**:**Once you “

**” the content in ELN, you**

*save***CANNOT**edit your equation.

**TIP:**copy-paste the latex equation code in a notepad or in ELN content. This way you can edit the formula by just copy-pasting the latex code back again in the equation editor.

- There are a lot of options you can use for editing your formulas.

**OPTION A.****1.**You can ‘Undo’ or ‘Redo”.**2.**You can use this to clear or erase the entire equation.**3.**You can use different colors while creating your equation. To put color to your equation, you can first select the color you want and then choose the functions to type.**4.**This option provides the functions for. To use the function just select the function you want and create your equation.**trigonometry, inverse trigonometry, logs, limits, and operator**

**OPTION B**- Here you will find options for:-
**1.**ย Here you can choose the style of the font you are using to create your equation.

**2.**Here you can choose the spaces between your equation characters. Just click on the spaces you want between your characters and then type your equation.**3.**Here you can see different symbols that could be used as mathematical operators.**Latex code****Description****Latex code****Description**ยฑ
