Overview of this book

Are you looking to start developing artificial intelligence applications? Do you need a refresher on key mathematical concepts? Full of engaging practical exercises, The Statistics and Calculus with Python Workshop will show you how to apply your understanding of advanced mathematics in the context of Python. The book begins by giving you a high-level overview of the libraries you'll use while performing statistics with Python. As you progress, you'll perform various mathematical tasks using the Python programming language, such as solving algebraic functions with Python starting with basic functions, and then working through transformations and solving equations. Later chapters in the book will cover statistics and calculus concepts and how to use them to solve problems and gain useful insights. Finally, you'll study differential equations with an emphasis on numerical methods and learn about algorithms that directly calculate values of functions. By the end of this book, you’ll have learned how to apply essential statistics and calculus concepts to develop robust Python applications that solve business challenges.

Preface

Vectors

Vectors are abstract mathematical objects with a magnitude (size) and direction (orientation). A vector is represented by an arrow that has a base (tail) and a head. The head shows the direction of the vector, while the length of the arrow's body shows its magnitude.

A scalar, in contrast to a vector, is a sole number. It's a non-vector, that is, a pure integer, real or complex (as we shall see later), that has no elements and hence no direction.

Vectors are symbolized by either a bold-faced letter A, a letter with an arrow on top, or simply by a regular letter, if there is no ambiguity regarding the notation in the discussion. The magnitude of the vector, A, is stylized as |A| or simply A. Now, let's have a look at the various vector operations.

Vector Operations

Simply put, a vector is a collection (think of a list or array) of two, three, or more numbers that form a mathematical object. This object lives in a particular geometrical space called...
