Why use MathCAD?

Mathcad is perfectly suited for engineering calculations. You work in Mathcad just as you would on a piece of calculation paper. The equations you write on a piece of paper can be entered into Mathcad just as they look on the paper, and just as quickly as you write them on the paper. The benefit of Mathcad is that your calculations are now electronic and can be archived, shared with coworkers, reused on other projects and updated as variables change. Another advantage of Mathcad is that your results can be used in further calculations. If the variables for the first result change, then all the calculations based on that first result are also immediately updated.

Mathcad is easy to learn. There is no programming language that you need to learn.With just a few simple instructions, you can begin using Mathcad.

With Mathcad all your calculations are presented on the worksheet. They are not hidden in cells as they are in spreadsheets. Also, all variables are named. You do not need to remember which cells the variables are stored in. This makes checking the Mathcad calculations much simpler.

These are all the great benefits and reasons for using Mathcad, but there is one more significant advantage to using Mathcad—Units! You can attach units to every number or variable used in Mathcad. Once a unit is attached to a number or variable, Mathcad remembers the unit. You can then display this variable in any unit system.You do not need to convert it. Mathcad does it for you. No more dividing by 12 to convert inches to feet, or remembering how many millimeters per inch. Mathcad does all of this internally. You can even mix unit systems. Units are discussed in great detail in Chapter 4—Units!

Mathcad can even replace your calculator. If you are doing your calculations the old fashioned way—using a paper and pencil, you can still use Mathcad to help with your calculations—such as adding or multiplying strings of numbers, evaluating equations, etc. The advantage is that the math stays on the screen until you close the worksheet. With a calculator all your numbers quickly disappear.With Mathcad, both the input and results stay on the screen. This way you can look back at previous calculations to check input or results.You can even change the input and get new results.
