Discrete mathematics with application 7th edition CHP 2 solution Pdf notes

 In the realm of mathematics, a solid understanding of discrete mathematics is essential. It serves as the foundation for various fields, including computer science, cryptography, and algorithm design. In this chapter, we dive into the basic structures of sets, functions, sequences, and summations, unraveling their significance and exploring their applications. Let's embark on this fascinating journey through the world of discrete mathematics.

Sets and Set Operations:

Sets form the building blocks of discrete mathematics, providing a framework for categorizing and organizing elements. A set is a collection of distinct objects, and these objects, referred to as elements, can be anything from numbers to letters or even complex entities. By employing sets, we can analyze relationships between elements and study their properties.

Set Notations and Operations:

To manipulate sets effectively, we employ various notations and operations. The most common notation is the roster form, where we list the elements enclosed within braces. Additionally, we utilize set-builder notation, which allows us to define sets based on specific properties. As for operations, we have union, intersection, complement, and difference, enabling us to combine, compare, and extract elements from different sets.


Understanding the properties of functions helps us analyze and manipulate them effectively. We delve into concepts like domain and range, inverse functions, composition of functions, and the pigeonhole principle. These concepts not only contribute to the theoretical aspects of discrete mathematics but also find practical applications in various fields.

Functions and their Applications:

Functions play a crucial role in discrete mathematics as they establish relationships between elements from two sets. A function takes an input (or domain) and produces a unique output (or range). We explore different types of functions, such as injective (one-to-one), surjective (onto), and bijective (one-to-one correspondence)

Sequences and Series:

Sequences are ordered lists of elements, where the order in which the elements appear matters. We encounter sequences in everyday life, from arithmetic progressions to Fibonacci numbers. In this section, we explore different types of sequences, their properties, and their applications in mathematics and beyond.

Summations and Series:

Summations involve adding up the terms of a sequence, and they often arise in mathematical analysis and algorithmic analysis. We delve into the theory of summations, discussing concepts like arithmetic and geometric series, sigma notation, and formulas for calculating sums. These tools enable us to analyze and evaluate the behavior of sequences and series.
