This Textbook Introduces The Vast Array Of Features And Powerful Mathematical Functions Of Mathematica Using A Multitude Of Clearly Presented Examples And Worked-out Problems. Each Section Starts With A Description Of A New Topic And Some Basic Examples. The Author Then Demonstrates The Use Of New Commands Through Three Categories Of Problems - The First Category Highlights Those Essential Parts Of The Text That Demonstrate The Use Of New Commands In Mathematica Whilst Solving Each Problem Presented; - The Second Comprises Problems That Further Demonstrate The Use Of Commands Previously Introduced To Tackle Different Situations; And - The Third Presents More Challenging Problems For Further Study.
