## MATHCAD: the symbolic result returned is too large to be displayed

(OP)

Problem with Mathcad: I have a symbolic matrix 9x9, and its determinant should be the argument of another function of only 1 variable like- f(x). Unfortunately when I evaluate symbolically the matrix, Mathcad returns the text: "the symbolic result returned is too large to be displayed but it can be assigned to a function or variable". That's what i want, but how to do it?

How do I assign it to a function?

Just do a normal assign, eg f(x):= |M| (or |M(x)|, doesn't work!

Please help!!! I'm getting crazy!! It's growing like a quiet private matter.

Thank you very much

Thank you (I apologize for my awful English)

Something like:

x:5 (guess value)

Given (start solve block)

|M(x)|=0

x:find(x) (end solve block and assign result back to x)

x:=20

Given

|M(x)|=0 (boolean equal ctrl+)

Find(x)=

Unfortunately when I write Find(x) it bencomes red and Mathcad says: "This variable is undefined"!! (I think it refers to x).

But it is obviously undefined!! It's symbolic, it's a variable, it can't be numerically defined!Is it wrong?

In the following file there is an easier similar problem resolved (the matrix is 3x3) and the function is graphed too: both problems are solvable, I'm sure.
