How do I number my equations?
Displayed equations in Writer documents can be numbered using a predefined AutoText:
- Type fn at the beginning of a paragraph and press F3. This will insert an AutoText containing a dummy formula and a sequence number. Now doubleclick the formula to edit it.
- If you want to number the equations by chapter you should
- Doubleclick one of the equation numbers.
- In the listbox Level choose the chapter level you want to number by.
- In the textbox Separator type a character to separate the chapter number from the formula number.
- If you want to modify the AutoText you should use the dialogue Edit-AutoText. You will find this AutoText in the group "Standard".
- You can also mimic the AutoText and number your equation manually by creating a table containing one row and two columns:
- in the first column you will insert the math object (your equation) and center it;
- in the right column, which will be reduced and right centered, you will place the equation number between two parentheses () by inserting a variable of type Text with the formula Text+1.
- You can refer to this equation by inserting a field corresponding to the equation of the table.
- In addition, if you select both, the reference and the table, you can make the selection an AutoText with the name Equation and abbreviation EQ (Ctrl_F3 AutoText New). Thus, if you type in the following Lotka's equation EQ, click on F3, enter the formula:
1= int_{0}^{infty} exp(-%rho x) f(x) p lsub{x}rsub{0} dx
- you will get both a numbered equation and the reference to it:
- in the following Lotka's equation (1):
