Introductionm0025027a8030686f_1528450127855_0Introduction

The teacher initiates a discussion about using formulas in text documents. Can the skill of inserting formulas be useful?

The teacher refers to the knowledge of the students. They name the formulas and operations they can write down.

Procedurem0025027a8030686f_1528446435040_0Procedure

Some text editors include built‑in equation editors – these are tools for editing mathematical formulas.

In order to start the equation editorequation editorequation editor in MS Word 2016, find the EquationequationEquation button, marked with the Pi symbolsymbolsymbol (π), on the Insert tab, in the Symbols group. You can also use the keyboard shortcut ALT + =.

[Illustration 1]

LibreOffice Math is an equation editor in Writer LibreOffice. In order to start it, click Object on the Insert dropdown list, and then select Formula.

Task 1

Run the text editor installed on your computer and check if it includes an equation editorequation editorequation editor.

In the equation editor included in MS Word you can create an equationequationequation by using the following methods:

- choose the equation you want from the gallery of exemplary or commonly used equations (e.g. the formula for the area of a circle),

- insert or write symbols,

- insert commonly used mathematical structures (e.g. a fraction, the radical symbolradical symbolradical symbol).

[Illustration 3]

In order to insert a mathematical structure, click the appropriate type of a structure (i.a. a fraction, script, radical or bracket) in the Structures group on the Design tab.m0025027a8030686f_1527752256679_0In order to insert a mathematical structure, click the appropriate type of a structure (i.a. a fraction, script, radical or bracket) in the Structures group on the Design tab.

To change the inserted equationequationequation, place the cursor within it. When you do, the Design tab is displayed on the ribbon. Then you can make the changes you want.

Task 2

By using an equation editorequation editorequation editor, insert the formula for the area of:

- a trapezium,
- an equilateral triangle,
- a kite,
- a circle.

The exemplary solution to the task.

P = \frac{(a + b) \cdot h}{2}, P = \frac{a^{2} \sqrt 3}{4}, P = \frac{1}{2 d_{1} \cdot d_{2}}, P = π r^{2}

Task 3

In an equation editorequation editorequation editor, write the following algebraic equationalgebraic equationalgebraic equation and then simplify it.

\frac{4 a^{2} - 4 b^{2}}{4 a^{2} + 8 a b + 4 b^{2}} =

The exemplary solution to the task.

\frac{4 a^{2} - 4 b^{2}}{4 a^{2} + 8 a b + 4 b^{2}} = \frac{4 (a^{2} - b^{2})}{4 (a^{2} + 2 a b + b^{2})} = \frac{(a - b) (a + b)}{(a + b)^{2}} = \frac{(a - b)}{(a + b)}

Task 4

Find on the internet and by using an equationequationequation editor insert the following formulas:

1. the formula for mass–energy equivalence (the Albert Einstein’s formula),
2. the formula for the increase in volume,
3. the formula for the wavelength,
4. the formula for the force of electrical interaction (Coulomb's law).

The exemplary solution to the task.

1. $E = m c^{2}$

2. $Δ V = V_{k} - V_{0}$

3. $λ = \frac{c}{f}$

4. $F = k \frac{q_{1} \cdot q_{2}}{r^{2}}$

Task 5

In an equation editorequation editorequation editor, write the following chemical reactions:

1. $M g + 2 H N O_{3} \to M g (N O_{3})_{2} + H_{2} ↑$

2. $F e_{2} O_{3} + 2 A l \to 2 F e + A l_{2} O_{3}$

3. $2 H^{+} + S O_{4}^{2 -} + P b^{2 +} + 2 N O_{3}^{-} \to P b S O_{4} ↓ + 2 H^{+} + 2 N O_{3}^{-}$

4. $3 (N H_{4})_{2} S O_{4} \to 4 N H_{3} ↑ + N_{2} ↑ + 3 S O_{2} ↑ + 6 H_{2} O$
