Dot in time derivative

Dot in time derivative

I would like to be able to put both one and two dots above x or y for time derivatives in Mathcad. Is this possible? I have been able to place two dots above a 'y' using the Windows Charmap, but it's really a poor solution.

Thank you in advance.

RE: Dot in time derivative

That's not possible using up to Matcad 13, 14 I don't know. But why don't you use y' and y'' - that you can do.

RE: Dot in time derivative

Thank you for the replies. I guess y' and y'' will have to do, although they usually do mean derivative with respect to x.

How do you type y' and y'' in mathcad? I don't seem to be able to write a regular ' as Mathcad just adds parentheses around the varibale when I hit the key. Perhaps it's due to my non-english keyboard layout? Among other things this means that all my shortcuts in Mathcad are different from the ones diplayed when you move the curser over an icon :( Luckily Matchcad does supply a "shortcut translation" list for my language (Danish).

You need to use the <ctrl><shft>k mode to enter literal and other characters into names.  Type:

Another alternative for y' and y" is to use the tick mark (`) that is on the same key as the tilde (~). The mark appears vertical in Mathcad.

RE: Dot in time derivative

I'll just repeat my 20 year old whinge in the forelorn hope that PTC are monitoring the site.

I only have very occasional use for a dot or over bar font but its frustrating when I do.  I've been waiting for 20 years for the authors of Mathcad to create a set of math fonts with dots, over-bars for mean etc.  

It would be easy enough to diy such a font but it would end up with as a dogs breakfast as soon as you transmitted files to other users.  The cost to PTC would be a few dollars.  The benefit would be that they could then finally claim that Mathcad is a complete mathematical tool without the work-arounds that still end up with mickey mouse presentation.

(I wouldn't spend money on a new version on Mathcad just to get the benefit - I've spent enough on Mathcad for what should have been in the version 1.1 which I purchased 1987/8 or thereabouts).
