    The present investigation entitled the "The learning of mathematics and cognitive processes in the solution of tasks with trigonometric ratios in the educational institution Pompilio Martínez de Cajicá, Colombia". The general objective was to establish the relationship between cognitive processes and the learning of mathematics in tenth grade students of the educational institute, Pompilio Martínez of Cajicá, when they solve tasks of trigonometric ratios, mediated by the pedagogical planning of didactic units. The research is quantitative, with a quasi-experimental design of descriptive transactional type. We worked with a sample of 299 students representing 22% of the population of the school. To collect the information, each student was given a multiple-choice questionnaire with a single true answer. The level of validity and degree of confidentiality was measured with test-retest and expert validation. Then, for the implementation of the didactic unit of trigonometric reasons seen through multiple lenses of the sample, a group of thirty, tenth grade students was taken. The results of the questionnaire allow to affirm that 48% of the students of the sample managed to highlight the dimensions of the learning of mathematics and the dimensions of the cognitive processes but 52% of the students have difficulties to raise and answer their own questions of mathematics. The results of the final evaluation of trigonometric ratios, revealed that 74% of the students of the experimental group learned the subject of trigonometric reasons, while, the control group only 49%, showed learning of the subject. From the research, it is concluded that there is a relationship between cognitive processes and the learning of mathematics, in tenth grade students of the educational institution, Pompilio Martínez, Cajica, Colombia; when they solve tasks with trigonometric ratios mediated by the pedagogical planning of didactic units.
