Question

Numbers in shown equations

Hi community,

sorry to disturb you and for the lack of skills in english, but i'm a grateful user of the program Mathcad 14. We are a hole group of students in Denmark, who wonders if the calculation service in the program can show the equation with the specific numbers used in the equation? The new policy rules in the Danish education environment demands numbers in the equation, but we can't find the specific settings to change this problem. We have made a well-functional template in the program, so we are in desperate need of help to change these settings.

Best regards

Peter Weller Nielsen

I guess the symbolic "explicit" command is what you are looking for.

Its by no means perfect for your purpose but it seems to be the only option if you don't want to type equations twice.

Unfortnately "explicit" is quite limited and you probably can't achieve all you want to see.

The symbolics is not aware of units and treats them as unknon variables.

Variables which have been manually assigned will be shown in the unit you had used when assigning. Self defined unist (like the dm) will be replace by the definition, if you use ";ALL". Otherwise you had to type "explicit,a,b,c".

If a variable was derived by some calculation and the was evaluated (like A3) it will only be shown in standard units.

    Great ! This is exactly what I was looking for, the "explicit" command.

    The variables, numerical values and answer are traditionally all presented in the equations of engineering calculations.

    There is a good reason for this. Having an explicit presentation makes the verification by engineers faster and more reliable.

    Verification is of utmost importance because practicing engineers have to take full responsibility for their calculations.

    What Werner has shown in his example seems to be perfect and already quite sufficient for many day-to-day engineering calculations.

    It would be nice if PTC could remove the limits that he mentions in his post.

    In my humble opinion, the "explicit" command is a very important tool for checking calculations. Thanks.
