This file contains an introduction to Mathcad. This introduction includes basic mathematical manipulations, graph preparation, solving for the roots of an equation and some use of solve blocks. Students can learn a few basic skills, enough to get them started in using Mathcad for their own studies and assignments. After completion of the exercises in this tutorial students should be able to do simple manipulations in Mathcad, create graphs, and annotate their documents. Students should also be able to prepare lab reports and do routine physical chemistry homework problems. The text was adapted by TJZ from a document created by Sidney Young, University of South Alabama. It includes material from a warm up document that Sidney used during the NSF supported 1997 "Workshop for Integration of Numerical Methods into the Undergraduate Physical Chemistry Curriculum Using the Mathcad Software" at the University of South Alabama, Mobile Alabama.
