STUDENTS’ PROBLEMS IN SOLVING TRIGONOMETRIC EQUATIONS

Abstract

 The aim of the study is to determine the abilities of 11th-grade students of trigonometric equations. The study used thematic analysis, one of the descriptive methods. Questions were prepared to consist of examples of trigonometry, including solutions to trigonometric equations. Data collection tools were applied to a random selection of  20 students at an education center. Descriptive analysis was used to analyze the data. According to the results, it was determined that some of the students participating in the study had problems using basic trigonometric formulas, trigonometric identities, and trigonometric equations. In addition, it is clear that the ability of students to decipher problem forms and application of factorization in the form of trigonometric quadratic equations is at a low level. It was found that students fail to correctly and adequately use their skills in solving trigonometric equations.
