In the comprehension of the subjects of physics and in the correct solution of physics questions, a substantial mathematical foundation is a pre-requisite. Thus, general mathematics course, which is the basis for advanced mathematics, is highly important for students. Limit, which is one of the subjects within general mathematics, plays a crucial role in the comprehension of the concepts of derivative and integral. In this study, first, the levels of prospective teachers regarding the limit and their misconceptions were determined, and their views on the content and methodology of the general mathematics course were asked. Various computer-generated visualizations were done for their deficiencies related to the limit in order to make the concepts such as limit on the right/left and infinite convergence more comprehensible, and students were instructed in a computer environment. As a result of the study, it was recommended that computer-generated visualization was helpful both in order to eliminate the misconceptions of prospective teachers and to teach the limit permanently and meaningfully. In the light of the findings of the study, it was also recommended that the content of the general mathematics course should be re-planned according to the needs of prospective physics teachers.
