"The objectives and the goals of our course have been met using this text. We want our students to learn the importance of seeking a numerical solution to a practical problem by applying relevant algorithms and analyze the speed of convergence, reliability, and validate the solution. We want our students to write programs using the same approach starting with a careful pseudo code before coding into the computer. We want our students to be exposed to the use of computer algebra systems. We want our students to be able to work on a variety of problems. This book has definitely met all our needs. This is why we have adopted it."
