As funÃÃes exponencial e logarÃtmica: uma abordagem para o professor do ensino bÃsico / The exponential and logarithmic functions: an approach for the teacher of basic education

CÃcero dos Santos Alves 26 June 2014 (has links)
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / Neste trabalho vamos fazer uma abordagem elementar sobre a funÃÃo exponencial visando entender o significado de potÃncias com expoente natural, inteiro, racional e irracional bem como as propriedades que fazem dela uma das funÃÃes mais importantes da MatemÃtica. Paralelamente, serà feita outra abordagem mostrando essas propriedades usando uma ferramenta poderosa da MatemÃtica: o cÃlculo diferencial e integral. TambÃm vamos tratar da funÃÃo logarÃtmica por ela ser a inversa da funÃÃo exponencial e por ser tÃo importante quanto esta. / In this work we make an elementary approach to the exponential function in order to understand the meaning of powers with natural exponent, integer, rational and irrational as well as the properties that make it one of the most important functions of mathematics. In parallel, another approach will be showing these properties using a powerful tool of mathematics: differential and integral calculus. We will also discuss the logarithmic function because it is the inverse of the exponential function and being as important as this.
