At my first steps in vectorcalculus i calculating a scalar line integral, but the concept how to do this is not  yet clear to me

I want to do a organised introduction in Maple  with the student and main vectorcalculus package
Is there some studymatrial to find for this ?
 

I did already some programmingexercises , but this sort of programming example i did not encounter in the programmingbook
How it is programmed in general lines ?
I do have a lot of small procedures to learn from

But it is too much asked here on the forum to explain all ins and outs for this procedure, because it is not that simple.

Read a tutorial from a user @les 185

Is this still valid this tutorial from 2015  in the current version of Maple ?
This seems to be userunfriendly.

There was a example in clickable calculus video showing 2D math about vectorcalculus and a positionvector fomulaes  noted with dots ( one and two dots)
How do i get this notation and is it usable in Mapleinput  1D ?
