In the process of solving mathematical problems, students often encounter mistakes in solving the problems given by their teachers. This research aims to diagnose students' errors in solving mathematical problems related to the topic of inverse functions at SMA Negeri 1 Trienggadeng. The approach utilized in this study is qualitative with an exploratory type. The research subjects consist of 22 students from X MIPA 3 class who have previously received instruction on inverse functions. Data collection techniques involve administering a test and conducting interviews with the students. The diagnostic test is the chosen assessment instrument, specifically designed to identify problems or errors experienced by students. Data analysis encompasses data reduction, data presentation, and drawing conclusions. The outcomes of this research indicate that students' errors in solving inverse function problems encompass conceptual errors, factual errors, principle errors, and operational errors. The most frequently occurring errors among students are principle errors and operational errors. Keywords: Student Errors, Inverse Functions, Diagnostic Test.
