How to write infinity on Geogebra
In this short tutorial I'll explain how to make the infinity symbol on Geogebra.
To write the infinity symbol on Geogebra press the key combination ALT + U on Windows or ALT + , on Mac.
This key combination writes the infinity symbol.
It is not just a graphic representation. Geogebra considers this symbol as infinity in mathematical calculations.
You can use the infinity symbol to calculate a limit of a function f(x) to infinity.
If you put the plus (+) or minus (-) sign in front of the infinity symbol you can calculate the limit for plus infinity (+ ∞) or minus infinity (-∞).
