Three important subjects in applied mathematics are combined in “Numerical Methods: Nonlinear Equations, Numerical Calculus, & Differential Equations” by D. James Benton. These topics are of great importance in applied mathematics. Nonlinear, integral, and differential equations are common in many scientific and technical fields, and the goal of the book is to assist readers in understanding and solving them. It offers several theories, concentrating on strong algorithms that perform well in situations involving one or more variables.
