Access to Spherical Coordinates points on a sphere

Hi,

Access to 3D Cartesian Coordinates of point B on a sphere is obtained: x (B), y (B), z (B).

In the Algebra section, we can change the view of the 3D Cartesian Coordinates / Spherical Coordinates. Is there access tools for φ and θ in Geogebra to Spherical Coordinates points on a sphere (R;φ;θ)? The Angle command gives an incomprehensible corner.

My exercises is in the file:

Thanks. The angle mismatch φ = arg (A) and the same angle in A = (R; φ; θ) -Bug?


You can see this in the attached earlier pictures Unbenannt.PNG

I understand that this is a shift!


But it should be the same displaying! Or somewhere there are special settings?
