| LibreOffice Mathன் Spoken tutorial க்கு நல்வரவு.
|-
|00.04
|இதில் tutorial, நாம் கற்கப் போவது

|-
|00.08
| Set operationகளை எழுதுதல்

|-
|00.10
| Factorials எழுதுதல் மற்றும் numbering மூலம் equationகளை Cross reference செய்தல்
|-
|00.16
|இதற்கு, முதலில் MathExample1.odt என்ற முன் tutorialகளில் உருவாக்கிய உதாரண writer document ஐ திறக்கலாம்.
|-
|00.29
|Here let us go to the end of the document and press Control Enter to go to a new page.

|-
|00.37
|And type “Set Operations: ” and press ''Enter'' twice.

|-
|00.42
|Now let us call Math.
|-
|00.46
|Before we go ahead, let us increase the font size to 18 point.

|-
|00.51
|Change the alignment to the left.

|-
|00.56
|Let us now learn how to write Set operations.

|-
|01.00
|Math has separate mark up to represent Sets, which are collections of distinct elements.

|-
|01.07
|Let us write 4 example sets in the Formula Editor window as shown on the screen:

|-
|01.15
|Set A with 5 elements

|-
|01.18
|Set B

|-
|01.20
|Set C

|-
|01.22
|And Set D equal to 6, and 7, with 2 elements each.
|-
|01.29
|Notice that to write the brackets for sets, we can use the mark up: lbrace and rbrace.

|-
|01.39
|Now we can write set operations such as unions and intersections.

|-
|01.45
|First let us write a union operation.

|-
|01.49
|The mark up for B union C is the same as we read it;

|-
|01.55
|and the resulting set is 1, 2, 6, 4, and 5, which includes all the distinct elements in both sets.

|-
|02.07
|The markup for an intersection operation is again the same as we read it.

|-
|02.13
|The intersection includes only the common elements from both the sets.

|-
|02.20
|So the result of B intersection D is 6.

|-
|02.26
|And we can also write: set C is a subset of set A, as every element in C is in set A.

|-
|02.39
|The mark up for this is C subset A.

|-
|02.46
|You can learn to write more set operations, by exploring the Elements window by clicking on the third icon there.

|-
|02.55
|Go to View> Elements> Set Operations.

|-
|03.03
|Let us save our work now.

|-
|03.05
|Click on File>Save.
|-
|03.10
|Now let us write Factorial functions.

|-
|03.14
|We will designate numbers 1 to 3 for the three formulae we are going to write shortly.

|-
|03.23
|These will help to cross reference them anywhere within the Writer document.

|-
|03.29
|Let us go to a new page by clicking three times slowly outside the Writer gray box.

|-
|03.37
|Press Control -Enter.

|-
|03.40
|Type “Factorial Function: ” and press enter twice.

|-
|03.45
|Now, we know how to call Math.

|-
|03.48
|But there is another way to bring up the Math object into the Writer.

|-
|03.54
|For this simply write ‘f n’ on the Writer document and press F3.

|-
|04.03
|We are now seeing a new Math object that says E is equal to m c squared;

|-
|04.11
|and along with that, the number one within parentheses, on the right.

|-
|04.18
|Meaning, we can cross reference this formula with the number 1 anywhere in this document; we will learn the details of how to do this later.

|-
|04.30
|For now, let us double click on the Math object

|-
|04.36
|And do the formatting. Font size 18 and Left Alignment.
|-
|04.43
|Okay, let us now write an example for Factorial.

|-
|04.48
|The mark up ‘fact’ represents the factorial symbol.

|-
|04.53
|So let us overwrite the existing formula with ours:

|-
|04.58
|5 Factorial = 5 into 4 into 3 into 2 into 1 = 120.

|-
|05.10
|Notice the mark up here.

|-
|05.12
|Let us write our next formula in a new Math object here.

|-
|05.17
|For this, let us first click outside this Writer gray box three times slowly.

|-
|05.26
|Press the down arrow key two or three times to go to the end of this page.

|-
|05.33
|And type ‘f n’ and press F3 to bring up the second Math object.

|-
|05.40
|Again, we will repeat the formatting

|-
|05.50
|and overwrite the existing formula with the factorial definition:

|-
|05.55
|N factorial is equal to prod from k = 1 to n of k.

|-
|06.05
|Notice the mark up ‘prod’ which denotes product, similar to sigma for summation.

|-
|06.13
|Now, let us introduce a third Math object just like the first two

|-
|06.24
|and rewrite the factorial definition as two conditional formulae as shown on the screen.

|-
|06.33
|Notice the mark up ‘binom’, which displays a vertical stack of two elements and helps with better alignment.
|-
|06.45
|Let us now see how we can cross reference these formulae.

|-
|06.50
|For this, let us go to a new page

|-
|06.54
|and type: An example of factorial is provided here:

|-
|07.02
|Now let us click on the Insert menu, and on Cross reference.

|-
|07.09
|In the new popup, let us select “Text” in the Type list.

|-
|07.15
|Then choose the first item in the Selection list denoting the first factorial formula we wrote.

|-
|07.24
|Now choose Reference in the ‘Insert reference tool’ list and click on Insert once and close.

|-
|07.35
|So the number one in parentheses has appeared next to our text. And we are done.

|-
|07.42
|Let us test it by simply clicking on this number;

|-
|07.47
|And notice that the cursor has jumped to the location where we wrote the first formula.

|-
|07.54
|So this is how we can cross reference Math formulae anywhere within the Writer document.

|-
|08.01
|Let us save our work.
|-
|08.05
|Here are some reference links for Math:

|-
|08.10
|Download guides at libreoffice.org documentation link.

|-
|08.17
|You can also visit the following website ''help.libreoffice.org/''Math for more information on Math
|-
|08.24
|And finally, here is an assignment for you. Use the Writer document.

|-
|08.29
|Using the example Sets in this tutorial: check if A union ( B union C) is equal to (A union B) union C

|-
|08.44
|Write the results of A minus B

|-
|08.47
|And cross reference the second and third factorial formulae in the Writer document
|-
|08.54
|This brings us to the end of this tutorial on Sets, Factorials and Cross Referencing in LibreOffice Math.
