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.
