Most of these questions are also answered by LyX's Math manual that you find in LyX's Help menu. §1. How do I put normal text inside a mathematical equation?Type \text and then press space while inside the equation to enter "math text mode". §2. Equation numbering doesn't work. Help?To number an equation, use Insert→Math→Display formula (Shift+Ctrl+M). Make sure you are not using inline formulas. Place the equation on a paragraph of its own, and then insert a label (Insert→Label) inside the blue box of the equation. §3. How do I make a cube root (or higher)?Type "M-m r" or \root to insert a root box. Use the cursor keys to navigate the entry boxes. §4. How can I change the appearance of limits in integrals etc?M-m l (or Alt-M l or Edit→Math→Change Limits Type) toggle between the two commands \limits and \nolimits. (You can write the example in the following way: \int \limits _b ^a
For integrals the limits are always set beside the operator ( nolimits-mode ). For sums the limits are set beside the operator in inline formulas and over/under them (limits-mode ) in dislay-style formulas. So M-m l has nothing to do with inline ore display-style mode.
For a detailed explanation, please refer to Help→Math, section 10.2 Operator Limits. §5. How can I add a matrix to a math expression without using the math-panel?
§6. How can I remove an equation label?Enter the equation and press M-m n. Pressing M-m n once more will show the equation label again. But how do I remove the label complete? I'm not allowed to set the label to nothing. You can try switching the 'display mode' on/off - while inside the equation, select Insert→Math→Display Formula twice, or use the corresponding keyboard shortcut (Ctrl+Shift+M). Note that this way the multiline (achieved by Ctrl+Enter) can be lost. §7. How can I stack math symbols? I want one symbol on top of the other.Use the LaTeX-command \overset{symbols above}{symbols below}. Here an example for an "a" over a maltese-symbol: \overset{a}{\maltese}
You can enter this command in TeX-mode or in a formula. §8. How can I write an inline formula (inline math) in the style of a display formula (bigger symbols etc?)Wrap it inside the command: \displaystyle §9. How can I add a tag/comment/note etc to a display equation?Try adding \tag{a comment} in ERT in the equation. (I've not tested this myself since I'm on Windows now). Note: Make sure to switch on "Use AMS math" in Layout→Document for this to work. §10. How can I reuse a number in a display equation?Use the comment tag to add a cross reference to the equation that you want to reuse. Instruction video. << | FAQ.PageList | >> |
