INTRODUCTION . 

INTRODUCTION #1

Mathcad  is computer software primarily used to combine a variety of different elements (variables, descriptive text, and supporting imagery) into the form of a worksheet, which is easy readable. This allows for simple manipulation of input variables, assumptions, and expressions, which in turn update in real-time. 

Mathcad provides hundreds of operators and built-in functions for solving technical problems from the simple to the very complex. It can be used to perform numerical calculations or to find more general symbolic solutions. In short time.

INTRODUCTION #2

First introduced in 1986 on DOS, it was the first to introduce live editing of typeset mathematical notation, combined with its automatic computations.

INTRODUCTION #3

ADVANTAGES . 

Advantages #1

Easy to link with cad , excel , pdf.. and other Files

Advantages #2

Using a smart Units,easy convert to any unit system.

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

You can even mix unit systems .

Advantages #3

Easy plotting 2D&3D&polar curves, graph fitting , contours graph … ,

Advantages #4

Simplifying expressions can make a differentiation ,integration , expand.., ) .

Advantages #5

Solving logical functions and systems of equations up to 50 equation and unknowns .

Solve up to 50 simultaneous equations in 50 unknowns .

Equations not restricted to linear equations

Allows equations and inequalities

Advantages #6

Finding roots of quadratic and polynomial equations

MATHCAD VS EXCEL . 

MATHACD VS EXCEL

Take a long time to write the equations.

Take a long time to understand the equations.

MATHCAD EXCEL Take a few time to

write the equations. Take a few time to

understand the equations.

EXCEL… No “units” management Live calculation but formulae hard to

read No support for advanced math

calculations Calculus Differential equations Etc….

=U15+1/(1-C$8)*((1+C$8)*H15*1000/ (2*(AF15+AG15)*CA15)-C$8*J15*1000/(AG15*BZ15))

Spreadsheets:

Right Tool for the Right Job: Mathcad versus Excel

MATHCAD …Live calculations expressed in natural, easy-to-read Math notation

Full support for units

Full support for advanced Math calculations

DISADVANTAGES .

Disadvantages

Does not display tabular data as cleanly as Excel.

Requires using a Mathcad program to repeat the analysis steps with different parameters.
