The purpose of the study was to test the effectiveness of the application of the first and second derivatives to analyze the mathematical functions in future teachers of Mathematics and Physics at UNHEVAL; for this, a cause-effect study and quasi-experimental design was carried out, hoping to optimize the learning of functions in a graphical and analytical way, by means of the exact location of the maximum and minimum points, inflection, determination of the concavity up and down, and others; we worked with a sample of 114 students, of them 73 units of analysis were control and 41 experimental; the data were collected with the written evaluative test, and they were processed obtaining descriptive statistics that allowed to say that the value Z = 7,09 is higher with respect to the critical z = 1,96 at 95% reliability, which allowed to reject the null hypothesis and accept the research hyp...

The objective of the study was to evaluate the incidence of the application of trigonometric functions in a heuristic mode, on the cognitive development of adolescents from Cauri. In this sense, the autonomous variable was applied to the dependent variable to generate an effect of improvement in cognitive development. The study had an explanatory level, basic type and quasi-experimental design. The population was made up of 335 young people from Cauri, from which a non-random sample of 46 was selected, who were grouped as follows: 20 in the experimental group and 26 in the control group. The data were collected through three evaluative written tests, each with 10 propositions to develop. The data obtained were processed in Microsoft Excel, which allowed the calculation of the statistics corresponding to the descriptive and inferential analysis. The results showed that the test T value is...
