I want to place exact lines, for example a line crossing a circle or a rectangle. How is it possible to connect a line to a mathematical correct point. Which will show clean an correct no matter how far I zoom in?
It depends on the mathematical point. Do you already know how to calculate it? Or is that that part you're stuck on?
Of course you can draw a circle or rectangle using Ellipse or Rectangle tool. And you can draw a line with either Pen/Bezier or Pencil/Freehand tool.
But it would be up to you to calculate the point. Once you have the point....it sounds like you mean a point on a circle or rectangle? Or do you mean a point in a circle or rectangle? Anyway once you have the point, it should be easy from there.
A lot of Inkscape users are really experts in geometry. They can figure out those visual ways to calculate a certain point (or line or area), you know start with a circle, and put a triangle with the apex here and draw a straight line there, and make an arc, and bing, bang, boom, there's the answer! I know I use geometric principles (at least what I can remember from school so long ago) all the time, with Inkscape.
Or are you talking about plotting a function or equation, like on a graph? Inkscape can do that as well, but the user needs to know the formulas or equations. Inkscape can't generate them (at least not that I know of).

Hello ,
I want to place exact lines, for example a line crossing a circle or a rectangle. How is it possible to connect a line to a mathematical correct point. Which will show clean an correct no matter how far I zoom in?
I want to extend lines until crossing an object.
I didn’t manage to do this in Inkscape.
best regards

Snapping assists in placing nodes and objects with great precision.

As Tyler Durden said + grids and guides features.
Personally, I frequently use the object-to-guide function (Shift+G) and snapping to guides to perform complex alignments.
There's also an extension that draws tangents, if that's what you need: https://github.com/Rhysun/inkTan
