This classic text offers a solid and concise introduction to the calculus of finite differences and difference equations, with a wide variety of worked examples and practice problems. It is a great resource for students of applied mathematics, computer science, and engineering who want a firm grasp of discrete methods.
To deepen my understanding of this material, I have been working through the books exercises and writing up detailed solutions as I go. This is an ongoing project that currently includes solutions to selected problems across several chapters. The focus is on clarity, correctness, and making the underlying methods easy to follow.
Students who are unfamiliar with this text can learn more about it here.
You will find both conceptual explanations and step-by-step computations. The material is especially helpful for self-learners or anyone reviewing this subject. Ive made a preview version of the solution manual available here.
As always, I welcome feedback — especially if you find errors or unclear explanations. Contributions and suggestions are appreciated!
