to change variable by its value

[canaryi]

Hello!
How can I change variable by its value??

Thanks!!


Example:
U:=230 V
I:=25 Amp

When I write: P:= U * I I would like to see: P:= 230 * 25

Use the symbolic menu "explicit" command

P:=U*I explicit,U,I >

will display as:

P:=U*I explicit,U,I > 230 V * 25 A

various other display options are available by right-clicking the expression.

pstuckey,

I have Mathcad Ver. 11.2a and on the symbolic menu, I don't have an explicit command. What version do you use?

Is that technique available in ver. 11.2a in some other form?


regards,

You found a reason to upgrade to Ver. 13. Explicit is a new feature.

EXPLICIT is a new function introduced in v12

Yes Explicit is a new function. One caution about upgrading though, the transition from MC11 to MC12 was pretty bumpy and many, many worksheets and techniques that worked in MC11 no longer work in MC12/13. And if you do decide to upgrade go to MC13, don't bother with MC12.

Agreed, v12 is a BAD puppy!!
