System Requirements
|
This tutorial is recorded using,
|
Slide:
Prerequisites |
To follow this tutorial, learner should be familiar with Math interface.
|
Slide:
Code Files |
|
Open the MathExample1.odt | Let us first open the MathExample1.odt file. |
Double click on the gray box.
|
Double-click the gray box in the Writer window.
|
Only narration | Let us learn how to write Greek characters using Math.
Greek characters like alpha, beta and others are common in mathematical formulae. |
Point towards the Elements window.
|
We don’t find these characters in the Elements window.
|
In FEW, press Enter, type %alpha newline `%beta newline | To write lowercase characters, type the name of the characters in lowercase.
|
In FEW, press Enter, type %GAMMA .
%THETA newline. |
To write uppercase characters, type the name of the characters in uppercase.
|
Click on Tools menu on top, click Symbols. | There is yet another way to enter Greek characters.
|
Point to the Symbols dialog box.
Select Greek under Symbols.
|
Symbols dialog box appears.
|
Click on the Greek letter alpha from the list.
Point towards the name of the letter.
|
Click on Greek letter alpha in the box.
The name of the selected letter is shown below the box.
|
Click on the Insert button in the Symbols dialog box to insert the symbol.
|
Now click the Insert button in the Symbols dialog box to insert the symbol. |
Click on the Greek letter from the box.
|
Similarly, insert other Greek letters given in the box. |
Click on the Close button. | Let’s close the Symbols dialog box, by clicking on the Close button. |
Point to the markup for the Greek letters in the Formula editor. | Notice that the markup for the Greek letters is shown in the Formula editor. |
Point towards symbols icon
Close the Symbols dialog box, by clicking on the Close button. |
We can also insert Greek letters using the Symbols icon on the Standard toolbar. |
Click Save on the standard toolbar. | Let us save the file now. |
Slide:
Assignment |
Pause the video and do this assignment.
pi is similar or equal to 3.1415.
|
Click anywhere in the Writer area.
|
Let us now write the steps to solve a quadratic equation.
|
Type: Solving a Quadratic Equation and press Enter twice.
Show the text editor with the equations. Added the Quadratic-Equation.txt in Code Files for copying-pasting the equations. |
Let us type: Solving a Quadratic Equation:.
|
Click Insert >> Select Object
>> Submenu >> Select Formula.
|
We will now call Math application.
From the submenu select Formula option. |
Point to the equation. | Let’s write the markup for the quadratic equation that we want to solve. |
Click on Format menu >> Select Font Size.
In the Font sizes dialog box >> Change the Base size to 16 pt >> click OK button. |
Let us change the font size to 16 point.
|
Click on Format menu >> Select Alignment.
Under Horizontal click Centered option. Click OK button |
Let us change the alignment to Centered. |
In FEW, type:
2x ^ 2 - 7 x + 3 = 0
|
In the Formula editor, type the markup as follows: 2 x squared minus 7 x plus 3 = 0.
|
Press Enter and type:
Quadratic Formula: newline Press Enter. |
Press Enter and type Quadratic Formula:.
|
Only narration | It is a good practice to break a complex formula into simple elements.
|
Type:
sqrt{b^2 – 4ac} newline newline. |
First we will write the innermost square root function.
|
Type { -b +- before the above equation and } at the end. | Next, let us add minus b plus or minus to the expression.
Then put the expression within curly brackets. |
Type { before the above equation, and } at the end.
|
Let us add another set of curly brackets to make the expression a numerator.
|
Type ~ before and after = sign.
~ = ~ Point mouse over FEW, ~ symbol next to ‘x’. |
Add blank spaces surrounding the equal to sign. |
In FEW, type:
newline newline Where ‘a’ is` the` coefficient` of` the` x^2 term, ~b `is `the ` coefficient` of` the` x` term, ` c~ is `a` constant` newline newline
|
Next let us type the rest of the text as follows in the Formula editor.
‘b’ is the coefficient of the x term. ‘c’ is a constant followed by a newline.
|
We` can` solve` the equation` by` substituting` 2 `for `a,` -7` for` b,` 3` for` c newline newline. | Now type the following line.
|
Press Enter twice and type
x~=~ {{ -(-7)+-sqrt{(-7)^2 - 4(2)(3)}}} over {2(2)} newline newline
|
The markup after the substituting the values is as shown.
|
Point to the quadratic equation. | Now let’s solve the quadratic equation to get the values of x. |
x~=~ {{7+-sqrt{(49- 24)}}} over 4 newline newline
|
Type the following lines to show the values of x.
|
x~=~ 3, ~ ~ x~=~ 0.5 newline newline | Here are the values of x. |
Ctrl + S | Let us save the changes. |
Narration only: | With this, we come to the end of this tutorial.
