This book accompanies the do-it-yourself course Calculate & Communicate with PTC Mathcad Prime 3.0. In this course you will learn to use large parts of applied mathematics on a computer. You will also learn to write up your calculations in such a way that others will be able to follow and use what you are doing.
The course consists of 25 interactive lessons, each accompanied by at least one computer exercise. You must download these from the PTC website. The lesson files are read-only, so you can practice without really changing them. (You can save your own files under a different name.) Each lesson, with exercises, should take between a half and a whole hour. The lesson will give you an idea of what can be done -you will need more time to practice using it on real problems. Files with answers to the exercises are available, but we advise you not to look at these before you have tried the exercises yourself.
