The object of this book is to quickly teach an electrical engineer or technologist how to use Mathcad. Mathcad simultaneously solves and documents calculations. It is oriented toward non-programmers who need to solve numerical engineering problems. Users like Mathcad because its programs follow the natural format of manual calculations. Complete keystroke-to-keystroke details are provided for problem solution and documentation. The reader learns by example. As a calculating tool, Mathcad solves equations. The equations are entered into Mathcad in a format similar to that used in manual calculations. It will solve mesh equations with real or complex numbers and will solve differential equations. Outputs can be numerical or graphical. Mathcad will also do symbolic calculations, meaning that it can reduce complex systems of equations to simpler equations. Documenting calculations is a major reason that Mathcad is used in modern industry. Calculations that in the past might have been recorded in notebooks, or even on easily lost scraps of paper, are now done with Mathcad to take advantage of the accuracy, neatness, traceability, and standardization it provides. Mathcad is available in a free 30 day demonstration version. The key features of Mathcad can be learned in 30 days.
