How do you calculate a straight line on a curved surface?
i.e. Drawing a line on an orange. While we're at it, is it possible for a plane to be curved? Obviously non-euclidean geometry.
It is possible to draw a Euclidean tangent line to a sphere, but once you translate the line onto the plane, it will become a curve. In non-Euclidean geometry, the idea of a line is different (especially the idea of "straightness"). The coordinates are given as
x = cos(θ)(rcos(φ))
y = sin(θ)(rcos(φ))
z = rsin(φ)
where r is the radius, θ is the longitude, and φ is the latitude.
