Display function/equation for graph elements

Attached is a file in which you can calculate missing lengths or angles for different given situations, to control manually maded calculations. Maybe this is what you are lokking for. I gues dutch won't prevent you to get out of it and/ore use and adapt. zijde = side and hoek = angle and that's about it...

Hi chris,

thank you for this nice little tool. Unfortunately, it does not fulfil my needs. I think I have to clarify what I'm aiming for:

I draw a geometric figure as in the attached example. Here I can see the length of line f and the value of angle alpha. Now I need an output that gives me f as a function of alpha (like f(alpha) = c*alpha, where "c" can be anything like sin, cos, numbers, ...). I think GeoGebra is doing all this in the background, otherwise I wouldn't be able to see values for f and alpha in the drawing, right?

Hi,

Hi,

do you want something like that ?

with fs(x) = FitSin[listeM]

move point C...

Hi Patrick,

that is just amazing! I came here hoping someone could give me a hint and you just delivered the whole solution :D! Thank you so much! I'm a complete beginner with GeoGebra so I will need some more time to really understand how you did that. But it's definitely the right thing and a good starting point for me.
