Description
Special functions first emerged as classical tools for solving difficult equations in mathematics and physics. With the rise of modern computation, their role has expanded far beyond closed-form solutions, revealing rich structure, deep interconnections and remarkable practical power. This book traces that evolution by pairing theory with the computational capabilities of Wolfram Language, allowing readers to move seamlessly from definition to analysis, visualization and numerical exploration. The text begins with the historical development of special functions and the foundational methods used to study them, including symbolic evaluation, analytic continuation and high-precision numerical computation. Carefully designed exercises encourage readers to experiment, compute and verify identities on their own, strengthening both intuition and theoretical understanding. As the chapters progress, the book explores the major families of special functions, including gamma and zeta functions, special integrals, Bessel and Airy functions, orthogonal polynomials and hypergeometric functions. Advanced topics follow, covering elliptic and Heun-related functions, multivariate generalizations such as Appell functions, and unifying superfunctions like the Meijer G- and Fox H-functions. While these topics are central to many areas of mathematics, physics and engineering, they are often underrepresented in traditional university curricula. This book is designed to fill that gap by integrating theory with practical computation and visualization. This textbook concludes with both a summary "nutshell" chapter to be used as a study guide and a sample exam. Readers can also download the free, interactive ebook edition to engage with live Wolfram Language code. Additional materials, including videos and quizzes, can be found online in the companion Wolfram U course. Contents What Is a Special Function?
