#### Overview of this book

Python, one of the world's most popular programming languages, has a number of powerful packages to help you tackle complex mathematical problems in a simple and efficient way. These core capabilities help programmers pave the way for building exciting applications in various domains, such as machine learning and data science, using knowledge in the computational mathematics domain. The book teaches you how to solve problems faced in a wide variety of mathematical fields, including calculus, probability, statistics and data science, graph theory, optimization, and geometry. You'll start by developing core skills and learning about packages covered in Python’s scientific stack, including NumPy, SciPy, and Matplotlib. As you advance, you'll get to grips with more advanced topics of calculus, probability, and networks (graph theory). After you gain a solid understanding of these topics, you'll discover Python's applications in data science and statistics, forecasting, geometry, and optimization. The final chapters will take you through a collection of miscellaneous problems, including working with specific data formats and accelerating code. By the end of this book, you'll have an arsenal of practical coding solutions that can be used and modified to solve a wide range of practical problems in computational mathematics and data science.

Basic Packages, Functions, and Concepts

Before getting started on any practical recipes, we'll use this opening chapter to introduce several core mathematical concepts and structures and their Python representations. In particular, we'll look at basic numerical types, basic mathematical functions (trigonometric functions, the exponential function, and logarithms), and matrices. Matrices are fundamental in most computational applications because of the connection between matrices and solutions of systems of linear equations. We'll explore some of these applications in this chapter, but matrices will play an important role throughout this book.

We'll cover the following main topics in this order:

• Python numerical types
• Basic mathematical functions
• NumPy arrays
• Matrices
