摘要：This study is a follow-up of the research, in which the researcher investigated relationship between students’ understanding of functions in Cartesian and Polar Coordinate Systems. Teaching of polar transformation and polar functions was included in the context of transformation concept in the course of Analysis II in a mathematics education program of an education faculty. This teaching process was designed in line of literacy in which the previous study was included. It was showed in the literature that the students who was not given the concept of polar functions could not transfer the function concept to polar coordinates and they use polar coordinates by memorize. It was aimed to examine Analysis II students’ constructions of polar functions in this qualitative study. For data collection, open-ended test and clinical interview techniques were used. Data was analyzed by using the content analysis technique (Yıldırım ve Şimşek, 2003). It was concluded that polar function concept was constructed. Moreover, it was seen that students’ construction of polar functions and their understanding level of function concept were directly related.
关键词：polar functions; polar coordinates; function concept.
