Abstract: The purpose of this study was to investigate the forms of errors made by students in solving trigonometry problems and their causes. This research method is descriptive research, with research subjects are high school students who have studied trigonometry. To find out what mistakes were made in solving trigonometry problems, students were given tests and interviewed to find out the causes of errors. The results showed that there were 16 forms of errors in solving trigonometric problems, which were further classified into three types of errors, namely conceptual errors (86.7% students), principle errors (53.3% students) and algorithm errors (43.3% students). The main cause of students making mistakes is because students do not understand the concept of trigonometry.
