“…A etimologia da palavra Trigonometria revela "pistas" sobre como utilizá-la, suas aplicações e a importância de conteúdos na Matemática e em outros campos científicos-tri (três), gonos (ângulos) e metron (medir) (RODRIGUES et al, 2022). A trigonometria é um ramo da matemática onde os gregos e babilônios foram os pioneiros a analisar e desenvolver estudos sobre as relações existentes entre os lados e os ângulos dos triângulos retângulos enquanto tentavam resolver os clássicos problemas de astronomia (SILVA e LIMA,202).…”

The work deals with the substitution of a transcendental function by a polynomial one, determined through Newton's Interpolator polynomial, in a certain interval, so that the characteristics in that space have a performance similar to that of the original function. Research enables numerous applications in the scientific field, as polynomial functions allow better predictability in the display of their graphics as well as in the entry of analytical points and results that are easy to manipulate and display. Some examples of application in the calculation of integrals were presented, presenting the calculations and obtaining the interpolating function. A comparative table was displayed with four transcendental functions, presenting equally acceptable results. The substitution of these functions in the integral calculation allows results with errors with a possibly acceptable margin in pre-established intervals.

Introduction: In the teaching of trigonometry, in the subject of high school mathematics, presented according to the textbooks, bringing contents and forms of resolution with many difficulties and practicality for teaching students to find angle between the hands of a clock., has become a reality for millions of students and teachers around the world. Based on this reality, the teaching of basic education has undergone major transformations in its teaching structure with. Objective: To develop an equation to find the angle between two hands of a clock, to meet the difficulties faced by students and teachers of teaching mathematics in basic education, through innovative methodologies that will provide learning for students and contribution to the public school community of the Municipality of São Francisco/PB, Brazil. Methodology: To carry out this research, a sample was formed by a triple factorial involving: 4 schools, 5 teachers and 10 students, from the city of São Francisco/PB/Brazil. The public elementary schools chosen to be part of the research were: EEECI Dorgival Silveira, ECI Mestre Júlio Sarmento, ECI DR. Silva Mariz and E.E.E.F.M Celson Mariz, respectively. Conclusions: In general, the difficulties pointed out by teachers and students listed in this study are related to continuing education, the scarce literature that does not offer didactic material in favor of the development of new mathematical models that can help solve trigonometry problems with ease and speed on the part of students, and the lack of innovative methodologies for teaching trigonometry both in the eyes of teachers and students. Thus, there are many barriers in the teaching and learning of mathematics, requiring the development of new research that dynamically enables the teaching of this discipline
