here I pose a simple question. To make mathemathical formalism compact I need
2 activ symbols: Everybody knows the operator d/dx: It is called total derevative.
Derevation of a funktion with several varibles one needs the partial derevation and additionally
a time derevation , for example: p( point on top)
d f( q )/dt = ∂f(q)/∂q *dq/dt...........further partial drevations, if q vector
I need not text symbols but I need an activ operator : ∂/∂q and q( point on top)
I am working with Jacobi matrices but in Mathcad Prime 2.0 I cannot find anything.
Please, if anybody will read this, give me some ideas.

Manfred, I do hope you receive a response to your question. If you do not, I recommend re-posting your question as a discussion rather than a blog.
Seems like you should be able to just define a function that includes all of the partial derivatives and q as an argument?
Dear Harvey,
I beg your pardon, I was 14 days on holliday.
I left my password at home. So I could not answer.
I can tell you ; I have got a funktion of 2 m in length.
And I use at the end of my work the Lagrangian Equation of 2 nd kind.
There are in this equation 2 partial derivatives.
In Mathcad a partial derivation does not exist. One can do all with d/dx.
In the mathematical and physical space one can not do that.
I am aware now that engineers have there own tradition to do mathematics.
greetings

Vibron,
The snip below shows the functionality that I believe you are after, but I think you also want new symbols for the partial derivative operation. I can't help with that.
