Direct and inverse functions. Theory and problems with logarithms, powers, radicals.

Preparation for the Unified State Exam (EGE), competitions, and university education.
Such important concepts as arcsine, arithmetic root, logarithm of a number are, in a sense, related, as each of them is a special case of the concept of 'argument of a monotonic function'. This fact is actively used in the book, standardizing and simplifying the study of all concepts and their corresponding functions.
In Part I, the concept of 'argument of a monotonic function' is introduced and its special cases are studied according to a unified plan.
In Part II, inverse functions and their special cases are introduced and studied.
The theory is presented with the solution of many problems of varying difficulty. Exercises with answers for independent work, presented at the end of the book, will help you consolidate what you have learned.
If you are preparing for an exam, studying or teaching in school and university, or simply love mathematics, this edition is for you!
