This study aims to establish a brief historical approach to trigonometry, approaching from antiquity to the present day, and investigate the knowledge of students in the 3rd year East about the history of trigonometry in the municipality of Itaporanga-PB. For the theoretical framework we rely on authors as Boyer (1996), Mol (2013), and among other authors that depict the theme. This research was developed through a bibliographic research, highlighting the importance of the history of mathematics, based on the ancient civilizations, the contributions of some Greek mathematicians, trigonometry in the middle Ages with the Hindus and Arabs, to the present day in analytically. The research methodology is an approach of qualitative analysis, which was developed as the main part of the development and application of a questionnaire in order to investigate the students' knowledge of the history of trigonometry. The analysis of data collected by the questionnaire, in a way, showed that most of the students throughout their school life never heard the story of Trigonometry, and the minority who reported having heard were unable to comment.
