The world of mathematics is probably one of the most fascinating creations of mankind. The world of mathematics with a Computer Algebra System, like MuPAD, is even more fascinating. With MuPAd, we can develop mathematical concepts, explore them and visualize them with just a few simple commands. This book is a gentle introduction to MuPAD - a modern Computer Algebra System. The author introduces MuPAD step by step and shows how we can use it in various areas of mathematics. A large chapter of the book is devoted to the graphical visualization of mathematical concepts, and MuPAD graphics are also used extensively throughout the rest of the book. Each chapter of the book should be considered as a single workshop for MuPAd beginners. The whole book is a perfect resource for conducting workshops on using Computer Algebra Systems to explore, experiment with, and visualize mathematical concepts.
