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:

Hi Roman,

in french (Longueur[A] ; arg(A) ; alt(A) )

(in english Length(A) )

Thanks, but the arg (A) other than in A? What words arg alt abbreviations for?

These commands are not in Input Help!!!!!!

1

Altitude angle (for 3D points / vectors)

alt( )

1

Argument (also works for 3D points / vectors) arg( )

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

properties > 0° .. 360°

I understand that this is a shift!

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

Sorry, found !!! The problem is over, thanks
