Does there exist a textbook in Norwegian (bokmål and nynorsk should both be fine) that covers the more advanced mathematics (needed for calculus) from videregående (secondary school, includes both gymnasium and vocational lines), as well as basic calculus up to the level of integration and differentiation of functions in one dimension?
We are currently using Claudia Neuhauser's 'Calculus for biology and medicine', which has the significant flaw of being in English. Also, it does not cover the basics very well. The style is very verbose.
The course this is for is targeted for students of biology, geology, chemistry, etc. Many have very weak mathematics background; they have not taken the more advanced mathematics courses in videregående. I presume the additional cognitive load from using a book in a foreign language does not help matters.
A book written in Danish or Swedish might also help.
