The objective of this work is to evaluate the results of classes without and with the application of the theory of meaningful learning, using the GeoGebra software, in approaching the contents of sine and cosine functions. The data collection instruments were a diagnostic questionnaire, tests and a perception questionnaire applied to 14 university students, divided into Group A and Group B. In both, similar approaches to the mathematical contents were carried out, however, for Group B during the application of the didactic intervention, the software and some guidelines of Ausubel's Learning Theory were used, while for the other group it was only the traditional approach of the sine and cosine function contents. The use of the software enabled a connection between theoretical (or abstract) mathematics and practice, enabling a more detailed visualization of the graphs of the sine and cosine functions, so that it presented more advantages when compared to traditional classes. The groups did not perform well in terms of the applications of the functions, revealing the need to expand the didactic approach to this type of question by teachers at all levels of education.
