Os logaritmos

Abstract

This work is proposed to synthesize the contents of Logarithm, to use a quick reference of their Theorems, properties and settings. Displays the contents of two distinct ways: first we discuss the contents of the vision Lima cite Lima1996, which sees the content in a more conveying the importance of elementary logarithms by history and highlighting the central position occupied by the logarithms in science and its application. But the system of logarithms have certain disadvantages and because of these drawbacks, in Secondly we use the tools of geometric computation presented by Leithold cite Leithold2002 that will assist us in understanding of the statements and the reader in implementing the calculations arithmetic. Here the natural logarithm is defined as an integral and the natural exponential function is defined as the inverse of the natural logarithmic, so we can define a power an irrational number and a real number. Graphing these functions are also important for a preview of behavioral context of the function. The board and the logarithmic ruler logarithmic calculus are presented as tools motivating the application of logarithmic properties. Thereby want to leave a note for a good understanding in the study of logarithms, since some definitions are not valid for every whole must pay attention to the level and limiting the pool in which you want to work.
