Abstract
An important feature of students' understanding of algebra and trigonometry is the relations
and representations that are constructed between these two areas of school mathematics. In this
study we report one students' understanding of the concepts before and after two lessons. The
student developed knowledge about the. topics that appears to be consistent with what the
teacher was aiming at. However, in a problem-solving situation, the student activated
knowledge that was different and incorrect. The results provide tentative support for the
argument that students sometimes develop 'garbled knowledge'.
