E. Contharteze Grigoletto, E. Capelas de Oliveira

• We calculate the limit of a particular trigonometric functionAfter a question proposed by a student: can you show a particular result, involving a trigonometric limit, using the definition of limit? The answer to this question is the aim of this manuscript.in a case in which direct substitution results in an indeterminacy (zero over zero), in four different ways, showing that the definition is not always the best way to obtain a result.
