Make sure you undefine x numerically, before doing the symbolic. With x some range, the symbolic is trying to get a symbolic solution for each of the values of x, that takes time if x is a large range, and the symbolic result is going to be huge...

So put an

x := x

To the right and above your symbolic evaluation F1(x) ->

 

But, looking closer to your sheet, you have numeric data. What do you expect the symbolic evaluation to show?

Or is it just this:

    Thanks.  I didn’t realize I needed to include the coeffs in F1 since I had defined it above.  
    Again, thanks much.  I will do that.

    I may have another question tomorrow on how to combine it with a fourier integral symbolically.

     

    KucMeekes, you are always a big help!

    Is this not working because I am using Mathcad 15?
