Thanks for the presentation presented by Ilia Novikov. The presentation was very informative for me. 

Please share on the forum the Mathcad file presented at the webinar. Thanks.

We're glad you enjoyed the webinar! (As I write this, we have another webinar starting in an hour, Making the Move from Mathcad 15 to Mathcad Prime...)

Anyone can watch the Symbolic webinar replay, along with other recent Mathcad webinars (including the above one if you miss out on it), on-demand here: https://www.mathcad.com/en/resources/webcast/virtual-roadshow-replays/

 

I'm also attaching Ilia's two files here!

    From "Mathcad Prime 7 Symbolic Engine.mcdx" :

    I should think that this makes a stronger case:

    (Note that this is from Mathcad before version 14, where Maple is the symbolic engine and the default assumption for undefined variables is complex, as demonstrated by:LucMeekes_0-1629875651749.png

    )

    If you type this in Prime, without the assumption, and it still produces 0 as an answer, THEN you have demonstrated that the default assumption in Prime is for x to be real.

     

     

    Likewise:

    Further down:

    Neat!

    (Mathcad 11 doesn't support defining a local function to a program:

    )

    Now I wonder if/when Prime supports symbolic assignments in a program, so that there is a chance for building a function that symbolically solves ODE's with constant coefficients...
