You don’t show what you are doing o how should we know?

Chances are that you need to vectorize as otherwise |x| will give you the magnitude of vector x.

I tried to edit my post above to add a picture, but the forum did not let me do so. So I try it here:

Failed again :-(

Hmm, neither cop & paste nor saving the picture and adding it using the “Insert Image” icon in the toolbar worked.

Try to attach the picture but that can’t be a satisfactory permanent solution

This forum (like the previous) allows to copy an expression and simply paste it into the message box.

One expression at a time.

PTC and the forum software developer are not into making things easy for users…

If you want all in one picture, then grab a screenshot and paste the interesting portion of that:

Note that this is a limitation of Prime, because from Mathcad I can do it without intermediate steps:
