I have a slider that decides the value of A. It is very important for some of the other things in the worksheet.

How can ask Geogebra to mark the points A and -A in the x-axis?

Mark in what way?

as a tick.

like you have 0,1,2,3 in the axes. I want to have A and -A marked.

You want "A" and "-A"?

yes. and while it will read "A" and "-A", the positions will depend on the slider.

That is a pretty good question, how about half an answer?

It can be done easily with 2 sliders.

Tell me. Or suggest any other way I can make the worksheet convincing

My worksheet has two functions U(a) and K(a)

I want a caption like this "Total Energy = U(a) + K(a)" = U(a) + K(a)

The later part should evaluate to the numerical value

One question at a time.

How does this look for the first part?

Those are not ticks.

You want ticks that move?

Ticks are fixed positions on the x and y axes. Ticks do not move individually.

Hm, that is very bad.

I think you should see my ggb file to understand why I need that

You can post step by step instructions as I do in my tuts.

That will take a lot of time and I do not remember them

What is wrong with giving you the files?

If the file is not tremendous, use lycos.
