The emergence of the theory of ordinary differential equations, data from the late seventeenth century. In a first attempt to separate procedures were created to resolve, but it was clear that a large number of these equations in the act of finding its solution did not correspond to the classical methods, this is, express them through elementary functions of calculus so they could not be resolved. It was not until the nineteenth century that mathematicians realized that only a relatively small number of differential equations could be solved by applying elementary functions. In early date, one of the first who noticed this question was the mathematician Swiss-born Leonardo Euler that in 1768 developed the first numerical method for solving differential equations, subsequently developed several that in form generally follow the line left by Euler, until one of great precision and intense use is the iterative Runge-Kutta methods. This paper presents an analysis of both methods, developing their basic algorithms, programmed in Mathcad. Being able to check at the end of the degree of accuracy that has everyone in the numerical solution of differential equations.

In the research it is investigated about the performance of students in the course of mathematical thought from which is designed a teaching strategy supported by components such as mathematics education, variational thinking, triadic brain and skills as theoretical support in order to strengthen designing the function concept for future courses of calculus. The objective is develop an educational strategy focused on mathematical modeling for the strengthening the concept of function in the students of mathematical thinking course, in the night shift at the Jorge Tadeo University. The main purpose of this research is to establish the academic performance of students in a course of mathematical thinking to design a didactic strategy supported in the tricerebral and this modeling allows the consolidation of function concept. The method was conceived from the mixed approach through the application of the instrument, the information was collected as diagnostic test, notes review, workshops and testing to offer a joint vision and this continues with the proposal design. In conclusion, we could find that from our proposal is possible to consolidate of integral manner the metalanguage, the numerical competency and variational thought, in regard to the concept of function.

The intent of this article is to show techniques and best practices that can be implemented in a logistics process inside a supply chain, based on surveys completed in several small businesses of the beef industry in Bogota by the students of the study group ̈Improvement of the distribution by the association of small beef businesses of Bogota. This are focused on the supply chain, led by the investigation instructor Guillermo Enrique Montes Paniza of the Coporación Universitaria Republicana who is the author of the article; in order to identify the errors in the companies of the industry to suggest an improved distribution chain, since the aim of the industry to provide quality products for their client, which will provide benefits for the company while creating process improvement and reduced costs.
