This book compares the two computer algebra programs, Maple and Mathematica used by students, mathematicians, scientists, and engineers. Structured by presenting parallel both systems in parallel, Mathematica's users can learn Maple quickly by finding the Maple equivalent to Mathematica functions, and vice versa. This student reference handbook consists of core material for incorporating Maple and Mathematica as a working tool into different undergraduate mathematical courses (algebra, geometry, calculus, complex functions, special functions, integral transforms, mathematical equations). Part I describes the foundations of Maple and Mathematica(with equivalent problems and solutions). Part II describes Mathematics with Maple and Mathematica by using equivalent problems.
