ab: Summary: Students’ work with limits of functions includes the concept of
infinity. These concepts are complex but necessary for mathematics
studies. A study of student solutions to limit tasks was conducted to
reveal how students handled limits of functions and infinity at a
Swedish university. As a background to the students’ and teachers’
situations we have also analysed textbooks and curricula. One result is
that many students were unable to handle limits correctly. Some
students gave correct answers with incorrect explanations to tasks.
Textbooks used at upper secondary schools do not provide much theory or
tasks about limits and infinity, so most students new to university do
not have a well developed image of these concepts.
