As aplicações da função logarítmica e sua inversa

Abstract

This monograph shows a descriptive study of theapplication of logarithmic function and its inverse. The theme was chosen due to the singularity of its properties, which for some reason are theoretically known, however little known on the everyday life. With the porpoise of developing the visibility of these functions, the instrument used for such action it was a bibliographic research with a qualitative description. The aims of this research is to show the practicalities that these functions promote in the analyze of day to day situations. It was held a study, which covered many areas of knowledge as: quemistry, biology, geography and others, and these functions have aplicabilities with the intention of showing the versatility of them, with the porpoise of evidencing its utilities on the understanding of many daily situations. A lot of aplicabilities of the logarithmic functions and its inverse may be seen in this work and also a detailed study of its theoretical, and later it will be referred with math demonstrations of each model(when possible) together with the explanation of each coefficient described in the model mathematical situation. The visibility of the model it is so important because through the shown relations some examples were resolved. At this example, it was outstanded the implicit and explicit function through the mathematical model demonstration (when possible). But, regardless of how its manifestation happens it is visible that both kinds act in our lives playing a relevant factor to the understanding of some phenomenons. Nevertheless, we know that the logarithmic function and its inverse can act directly or indirectly in our daily life even in a comprehension of a day to day situation or in the comprehension of a natural phenomenon.
