Getting Started with Open Office .org 3 part 33. This Manual Book is for anyone who wants to get up to speed quickly with the latest version . “GETTING STARTED WITH ″ introduces all software programs of the OpenOffice bundle: Writer (word processing), Calc (spreadsheets), Impress (presentations), Draw (vector drawings), Math (equation editor) and Base (database). This book was written by volunteers from the community working through and is distributed under the CreativeCommon Attribution Licence | OOoMath provides scalable brackets. That is the brackets grow in size to match the size of their contents. Use the commands left and right to make scalable brackets. Markup Result left matrix a b c d right 1 b 1 c d Tip Use left and right to obtain square brackets. How do I make a derivative Making derivatives essentially comes down to one trick Tell OOo it s a fraction. In other words you have to use the over command. Combine this with either the letter d for a total derivative or the partial command for a partial derivative to achieve the effect of a derivative. Markup Result df over dx L dx partial f over partial y EL d y partial f over partial t 2 ELL d t2 Notice that we had to use squiggly brackets to make the Note derivative. Numbering equations Equation numbering is one of OOoMath s best hidden features. The steps are simple but obscure 1 Start a new line. 2 Type fn and then press F3. The fn is replaced by a numbered formula E mc 2 Chapter 9 Getting Started with Math 321 Now you can double-click on the formula to edit it. For example here is the Riemann Zeta function C FL 3 n 1 n You can reference an equation as shown in Equation 2 with these steps 1 Insert Cross-reference. 2 Click on the References tab Figure 283 . 3 Under Type select Text. 4 Under Selection pick the equation number. 5 Under Format choose Reference. 6 Click Insert. Done If you later add more equations to the paper before the referenced equation all the equations will automatically renumber and the cross-references will update. Figure 284. Inserting a cross-reference to an equation number Tip To insert the equation number without parenthesis around it choose Numbering instead of Reference under Format. 322 Getting Started with 3 3 Chapter 10 Printing Exporting and .
