A high school student sent us this neat problem on inverse functions. Thanks! The problem can be found in the book
Theoretical math 1.
Noen lærere som vil kjøre et avsluttende prosjekt hvor man sammenligner bøkene fra OpenMathBooks med eksisterende læreverk? Det kan være det vanker et gratis klassesett med bøker etter endt prosjekt. Ta kontakt!
OpenMathBooks on Bluesky! Will try to reach out with some updates on the project now and then and of course post some cool problems from the books.
