Given the theoretical-methodological limitations of Mathematics educators when teaching trigonometric content, this work intends to analyze how the initial training courses for Mathematics’ teachers in public Higher Education Institutions located in the Northern Region of Brazil are contributing to the construction of teachers’ knowledges for the approach of Trigonometry in Basic Education. Because of this, was adopted the Qualitative Research and the participation of Mathematics’ undergraduates from three institutions of Manaus’ City. Data collection took place virtually, with the application of a questionnaire and semi-structured interview, whose data were analyzed according to the Discursive Textual Analysis. The results indicate that such courses are supporting the mobilization of a repertoire of professional knowledge for the teaching of Trigonometry in educational practice. However, the imminent educators underlined a feeling of didactic-pedagogical unpreparedness and the lack of balance and coherence between the specific and pedagogical disciplines that introduce this object in their proposals.
