Exploration of high school students' reasoning in solving trigonometric function problems

Reasoning has been extensively studied by many experts. However, Research on student reasoning in trigonometric problem solving, particularly those related to logical thinking skills is still sorely needed. This study aimed explore students' solving function problems regarding skills. The research was conducted using a qualitative approach. subjects involved high school students Palopo, Indonesia. Based the ability test results, three were selected, namely with high, medium, and low abilities. instruments mathematical problem-solving tasks interview guidelines are valid reliable. Data collection carried out through task-based interviews think-aloud. results of study: (1) moderate abilities same every type question, always starting inductive then doing deductive (2) medium different initial identification. Subjects showed no mental activity problems. finding that subject first reasoning. In general, it concluded use patterns interchangeably
