Elementary functions and domain
Vitásek, Tomáš ; Pilous, Derek (advisor) ; Jančařík, Antonín (referee)
The aim of my bachelor thesis is to show the teachers and the students of educational mathematics the relation between the elementary functions and their domains and the methods of creating problems focused on finding the domain. In the chapter called "Zobrazení", I try to define and explain the terminology closely connected to elementary functions and their doma- ins which I use in the following parts. Crucial chapters are "Definiční obory elementárních funkcí" and "Návrhy úloh". In the first of those two chapters I thoroughly explain the algorithm of solving problems focused on finding the domain of elementary functions and I discuss what the domains of various elementary functions are like. In the second of those two chapters, I suggest functions fitting a concrete domain. The aim is to suggest functions in a way that a student taking their maturita exam in mathematics at high school would be able to solve the problem of finding the domain. Keywords: elementary function, domain, function composition.

Inversion of elementary functions
Vitásek, Tomáš ; Pilous, Derek (advisor) ; Kvasz, Ladislav (referee)
The main point of the bachelor thesis is to show mathematics students and te- achers the relation between elementary function and its inverse function, the approach how to find the inverse function and possible processes in designing inverse function tasks. In the chapter "Zobrazení", I define and explain ne- cessary terms, which are used in various parts of the thesis. Further, I discuss basic features of inverse functions. In the chapter "Inverzní funkce k elemen- tárním funkcím" first I discuss the invertibility of elementary functions, and then I describe the process of solving inverse function tasks in detail. In the chapter "Návrhy úloh" I show the proces of designing the task with defined difficulty, using the previously described knowledge. Keywords: elementary function, invertible function, inverse function.

Problem posing for limits of functions
Prskavcová, Pavla ; Pilous, Derek (advisor) ; Kvasz, Ladislav (referee)
Title: Problem posing for limits of functions Author: Pavla Prskavcová Department: Department of Mathematics and Mathematical Education Supervisor: Mgr. Derek Pilous, Ph.D. The aim of the thesis is to describe methods of limit problems solving and of posing new problems that are solvable by those methods. The first part of the thesis contains the necessary theory (definitions and theorems). In the second part of the thesis there are described the standard methods used for evaluating containing limits. The third part suggest ways of posing problems solvable by using elementary methods, based on the analysis of methods describes in the se- cond part of the thesis (without usage of the differential calculus). Keywords: limit, problem solving, problem posing, elementary function.

On impossibility of elementary integration
Zelina, Michael ; Pražák, Dalibor (advisor) ; Kazda, Alexandr (referee)
This work is devoted to studying of problem of (non)existence an elementary pri- mitive function of a given function. In the first place, we introduce the structure of a differential field and then we find a suitable way of formalizing the concept of the elementary function. This tools opens up the possibility to formulate and prove the crucial theorem which says what form an elemental primitive function must necessarily have if it exists. Then we use it to find the conditions for the existence of an ele- mentary integrals of two functions in a special but still quite general form. By using these conditions, we will show the nonelementarity of a number of more or less known integrals. 3
