Studio di funzione con derivata prima difficile .Come studiare il segno della derivata prima

Study of a function with a first derivative that is difficult to study With this lesson I propose a study of a function that apparently does not seem to be hostile, but when studying the first derivative several problems arise due to the fact that the numerator is not in a standard form. The study of the sign of the first derivative must be done with non-analytic methods. Specifically, we will find ourselves studying two auxiliary functions in order to be able to make the comparison between two graphs of two different functions and draw conclusions on the sign of the first derivative. The text was provided to me by a mathematics student, and I am happy to share my personal development. #salvoromeo #function #studyoffunction
