This October I should start my bachelor's in mathematical-technical software development at FernUniversität in Hagen, Germany. Since German is my 2nd foreign language (English is my 1st), I'd like to know if there are any books that cover the topics of Linear Algebra and Calculus/Analysis in a similar format that of Precalculus written by Carl Stitz and Jeff Zeagar? Mainly, the format is that there is a lot of text and nuanced explanations (many dislike this), plus plenty of problems.
The goal is to primarily use German textbooks and course material to study, but when and if necessary, I want to have something that I can fall back onto to gain more lucid understanding, at least for the first few modules until I become more comfortable with the German language.
Here is the link to Carl Stitz's and Jeff Zeagar's website where you can find links to their open-source pdfs: https://www.stitz-zeager.com/
Thanks a lot.
