Facharbeit: Formulas

This page was translated from German with AI. It has not been checked by a native speaker. Original page in German

Formulas do not belong in the paper as text. Important formulas stand centred on a line of their own, with a number at the right margin – then you can refer to “Equation (1)” in the text.

The video

In the video you see LibreOffice in the browser. The orange frame always shows where you click next. In other word processors the menus have slightly different names; the steps are the same.

Subtitles are available in ten languages. Choose them at the bottom right of the video.

Numbered formula in LibreOffice

Type fn, press F3: formula and number appear. Delete the sample formula, type the command, select it, Insert › Symbols › Formula (Einfügen › Symbole › Formel).

The formula T = 2π·√(l/g) centred, with the number (1) on the right.
The formula T = 2π·√(l/g) centred, with the number (1) on the right.

The commands resemble those of LaTeX: %pi for π, sqrt{x} for the square root, a over b for a fraction, x^2 for the exponent. Curly brackets group what belongs together: {4 %pi^2 l} over T^2.

The second formula automatically gets the number (2).
The second formula automatically gets the number (2).

The worksheet

Here you can see the worksheet for the video (in German). If there is a practice file, you download it above and work in your own word processor. The hints are printed upside down – turn the sheet only when you cannot get on by yourself. You can also open it as a PDF.

Task

What is the formula command for the fraction with numerator a + b and denominator 2?

Show solution

{a + b} over 2. Without curly brackets only b would be the numerator: a + b/2.

Keep learning with a language model

You are my teacher. I am learning to set formulas in LibreOffice Math (commands like %pi, sqrt{}, over, ^). Give me five formulas from physics or mathematics, one after the other, and let me write the command. Check it and explain mistakes briefly.

How this was made: The idea and the choice of topics are mine. A language model (LLM) drafted the script, the sample paper, the tasks and this page following my instructions. The screen recordings were made automatically by a script in LibreOffice (in the browser, with Collabora Online), which checked after every step that the setting was really saved. The voice was generated with Qwen3-TTS, modelled on my own voice.

The sample paper about the thread pendulum is invented, and so are the person “Alex Beispiel” and the two sources in the bibliography.
