1)How do I define the object?
A = sphere((0,0,0), 1)
How to cut off the domain that i need?
I'm a complete novice and failed to find the answer in the documentation.
2) What's the right way to draw a segment of a big circle between two points on a sphere given in spherical coordinates?Tue, 05 Mar 2019 22:43:54 +0100https://ask.sagemath.org/question/45675/subset-of-sphere-defined-by-inequalities/Comment by FrédéricC for <p>I need to draw several geodesics on a subset of a unit sphere, namely the set of all points with z-coordinate -0.5<z&lt;0.5< p="">
