Suppress Symbolic Solution in M15

I don't know if this has been noted before, but I managed (by accident) to suppress the display of a symbolic solve in M15 [Mathcad 15.0 (M030 [MC15_M030_20131216])]

Does this work in other versions of Mathcad?

    Interesting find.  It works for me in MC15_M010_20110622.

    Hi Stuart,

    Here is Mathcad 11:

    All reds are "This variable is not defined above".

    Hmm, interesting, Luc.  So, the symbolic evaluation of q works, but the definitions don't carry over into the numerical world.

    Yep, that's what it is.

    So its partly helpful in Mathcad 11.

    Wasn't aware of this. its nice and useful!

    It also works if you type the symbolic expression anywhere on the sheet, cut it out via Ctrl-X (including the RHS) and then type yor function name like q(a,b,c):= make a pair of parantheses and copy in the placeholder you just created.

    I like it!

    Yes, I forgot to add that bit.  Here's another interesting little morsel - try typing f(n)= after creating such a definition!

    All the same here in MC15 M045.

    It doesn't need to be so complicated, in Mathcad 11 I can:

    The result is the same.

    That is, by the way, the same method I use to plug symbolic expressions into programs.

    Interesting find! I see two problems though:

    1) Next time I will need this I will have forgotten how to do it.

    2) It's a useful, but undocumented, feature, so at some point it will be taken away from us

    1).  Of course.  Goes without saying. 

    2).  I'm tempted to mark your answer correct ...

    Stuart,

    In the Mathcad 15 M045 service release I have only no symbolical answer for "p(n)", for the rest all too most, as at you (please see PDF attached).

    Спасибо, Владимир.


    What does Prime do?  If it can't be directly implemented, does it still work in an imported (M15) worksheet?

    Please let "The System" keep our toys in later versions ....

    Hi

    With a little trick you avoid having the constants and variables  painted in red.

    I hope I understand your trick but it doesn`t work in my case and I don`t understand why.

    Hi, 

    I think that, in addition to the round brackets, the symbolic equal is not really needed.
