Noções de cálculo diferencial: uma proposta para o ensino médio

Abstract

In this work we have presented a proposal to introduce, early in the rst year of High School Education, the idea of the Rate of Variation of a Function either from the algebraic or geometric point of view and characterize the elementary functions (a ne, quadratic and exponential) from their variabilities (the form as a function increase and decrease). In this sense, it is very important to have a certain connection with the discipline of Physics, where the kinematics is a rich environment for this study. To conclude, we proposed an intuitive study of Limit of Sequence, which will allow us a more consistent approach of the important number of Euler that appears naturally in situations where the variation of a certain grandeur in a speci c moment is proportional to its value at that moment.
