During his life, hewould present three different solutions to the Problem ,which asks for an evaluation of the infinite series k= then, people have continually looked for new,interesting, and enlightening approaches to this sameproblem. Here, we present 5 different solutions, drawingfrom such diverse areas as complex analysis, calculus,probability, and Hilbert space theory.
