| 00:00 | Welcome to the Spoken tutorial on LibreOffice Math. | |
| 00:04 | In this tutorial, we will cover the following topics: | |
| 00:08 | Mark up language for writing formula and Formula formatting: Fonts, Alignment, and Spacing | |
| 00:18 | In the last tutorial, we introduced the mark up language for Math. | |
| 00:24 | Now let us learn more about Mark up language. | |
| 00:28 | Let first open a Writer document and then call the Math application inside Writer. | |
| 00:35 | If Writer is already open, then click on the Insert menu at the top and then click on Object and choose Formula. | |
| 00:46 | If Writer is not open, we can invoke it from the Windows Start menu. | |
| 00:55 | Using the Elements window is a very easy method of writing a formula. | |
| 01:01 | But directly writing the mark up language in the Formula Editor is a faster way of writing a formula | |
| 01:10 | Because markup language for a formula resembles the way we would read the formula in English. | |
| 01:18 | For example, to write ‘4 into 3’, , we just need to type in the Formula Editor window ‘4 times 3’ | |
| 01:28 | Before we go to the next example, let us insert a blank line here. | |
| 01:36 | Simply type the markup ‘newline’ and notice that a new line is inserted in the Writer gray box area. | |
| 01:46 | Let us type ‘Some more example formulae: newline’. | |
| 01:52 | For readability we will press the Enter key once. | |
| 01:57 | And write ‘x greater than equal to y’. | |
| 02:03 | Here we will also number the formulae. | |
| 02:07 | So we will type ‘1. x greater than equal to y new line’. Press enter | |
| 02:18 | Notice the Writer gray box has refreshed and the contents are centered. | |
| 02:25 | Next let us write: ‘a to the power of 2’. | |
| 02:30 | And the markup is: ‘2. 'a' arrow pointing upward 10’ new line’ and press Enter | |
| 02:42 | Notice the mathematical symbol in the Writer gray box. | |
| 02:48 | Now let us write ‘square root of 16 = 4’ | |
| 02:55 | Type ‘3. sqrt ‘16’ within curly brackets equals 4 new line’. Press Enter | |
| 03:06 | Notice this formula in the Writer gray box. | |
| 03:10 | Alright, now let us write a summation symbol for ‘a suffix n’, to denote a1 + a2 + a3 so on + ‘an’. | |
| 03:28 | And the markup is:, ‘4. sum a underscore n new line’. Press Enter. | |
| 03:37 | Now let us try an integral with a function. To write Integral f x d x, the markup is,‘5. int fx dx newline’. | |
| 03:54 | And notice the integral symbol in the Writer area. | |
| 04:00 | Let us save our work now. Go to File menu at the top, click on Save. | |
| 04:09 | Name the document as MathExample1. | |
| 04:15 | Now let us learn how to format the formulae we wrote . | |
| 04:21 | Notice that they are all centered and don’t have a lot of space in between them. | |
| 04:28 | We can use the Format menu at the top for making various format changes. | |
| 04:35 | Let us first align all the formulae to the left. | |
| 04:40 | For this, let us click on Format menu and choose Alignment. | |
| 04:46 | In the new window, choose the Left option. And click on the Ok button. | |
| 04:54 | Notice that the formulae are left aligned now. | |
| 04:58 | We can change the font style by choosing ‘Fonts’ under the Format menu. | |
| 05:06 | Notice the various categories here: | |
| 05:10 | We can set one type of font for variables, another type for functions, another for numbers and text. | |
| 05:23 | To modify the font style, click on the Modify button and choose the category Variables. | |
| 05:34 | Let us choose Arial Black in the list box and click on the Ok button. | |
| 05:43 | And let us save the font, by clicking on the Ok button here. | |
| 05:50 | Now notice the font changes in the Writer gray box. | |
| 05:56 | To increase the font size of the formulae, go to Format menu and click on Font Size . | |
| 06:06 | Let us increase the Base size to ‘18 point’. Click on OK. | |
| 06:16 | We can change the relative sizes of other categories such as the text or indexes or operators. | |
| 06:25 | We can also use the Default button to undo all the font size changes we made. | |
| 06:32 | Notice the font size changes in the formulae. | |
| 06:37 | Next, let us make changes to the spacing of the formulae. | |
| 06:42 | click on Format menu and choose Spacing. | |
| 06:48 | Let us change the spacing, line spacing and root spacing each to 20 percent. | |
| 06:56 | As we click on each spacing type, the image in the centre shows the location of the spacing type. | |
| 07:05 | Again we can choose spacing types from the various categories. To do this, let us click on the Category button | |
| 07:16 | Or use the Default button to undo our changes. | |
| 07:22 | Let us click on the Ok button now. | |
| 07:25 | And notice the spacing changes in the Writer gray box. | |
| 07:30 | More formatting is available in the Elements window. | |
| 07:35 | Let us bring up the Elements window from the View menu. | |
| 07:40 | Here, let us click on the last icon in the second row of categories. | |
| 07:47 | The tooltip here says ‘Formats’. | |
| 07:51 | Here, we can choose placements of subscripts and superscripts, alignments, matrix, new lines and gaps. | |
| 08:03 | Let us introduce a long gap in the fifth example, after the number 5 .Click after ‘5.’ | |
| 08:13 | Then from the Elements window click on Formats> Long Gap | |
| 08:20 | The mark up for long gap is the ‘tilde’ character. And for the short gap, it is ‘Tiray’ character. | |
| 08:29 | Notice the new gap after the number 5. | |
| 08:33 | So these are the ways we can format our formulae. | |
| 08:38 | Feel free to explore all the formatting options which Math provides. | |
| 08:44 | Okay, here is an assignment for you: | |
| 08:47 | In the Writer window, write the following formulae using Mark up. | |
| 08:53 | Use Elements window if necessary | |
| 08:57 | Summation of x to the power of 2 | |
| 09:02 | Sin to the power of x plus cos to the power of x = 1 (use the Functions category in the Elements window) | |
| 09:15 | Continued from the previous slide Write Summation from 1 to n of x. | |
| 09:23 | (use the Operators category to set the limits for summation) | |
| 09:29 | Change font to Arial and size to 18 point | |
| 09:35 | And Provide more spacing between the symbols. | |
| 09:40 | This brings us to the end of this tutorial on Mark up Language and Formula Formatting in LibreOffice Math | |
| 09:49 | To summarize, we learned the following topics: | |
| 09:52 | Mark up language for writing formula and Formula formatting: Fonts, Alignment, and Spacing | |
