描述This book gathers together a novel collection of problems in mathematical analysis that are challenging and worth studying. They cover most of the classical topics of a course in mathematical analysis, and include challenges presented with an increasing level of difficulty. Problems are designed to encourage creativity, and some of them were especially crafted to lead to open problems which might be of interest for students seeking motivation to get a start in research..The sets of problems are comprised in Part I. The exercises are arranged on topics, many of them being preceded by supporting theory. Content starts with limits, series of real numbers and power series, extending to derivatives and their applications, partial derivatives and implicit functions. Difficult problems have been structured in parts, helping the reader to find a solution. Challenges and open problems are scattered throughout the text, being an invitation to discover new original methodsfor proving known results and establishing new ones. The final two chapters offer ambitious readers splendid problems and two new proofs of a famous quadratic series involving harmonic numbers. In Part II, the reader will fi

Implicit FunctionsThe problems included in this chapter are about studying the existence and unicity of implicit functions of one or more variables defined by an equation or by a system of equations.

Derivatives and ApplicationsSince . is strictly increasing we get that . is injective. We also have that . is surjective and it follows that . is bijective. Since .(2) = 2 we have that .. From .(.) = .. − 3., . ∈ ., we can write ..(.) − 3.(.) = ., . ∈ .. Taking successive derivatives, one has that 3..(.)..(.) − 3..(.) = 1, 6.(.)..(.) + 3..(.) ⋅ ..(.) − 3..(.) = 0, . ∈ ..
