Time | Narration | |
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-
| |
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 us 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, mark-up 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 formula. | |
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 10. | |
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 dx, the markup is: 5. int f(x) 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 tool tip 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
