A solid one has a moment of inertia with a prefactor of two-fifths, and a volume element proportional to the sine of the polar angle and consisting of a distance, a polar angle, and an azimuthal angle make up the coordinate system named for these objects.
These objects give their name to the harmonic functions which give the angular part of solutions to Laplace's equation. A Schmidt corrector plate can be used to correct for an optical effect caused by these objects, which is eliminated at aplanatic points. A solid one has a moment of inertia with a prefactor of two-fifths, and a volume element proportional to the sine of the polar angle and consisting of a distance, a polar angle, and an azimuthal angle make up the coordinate system named for these objects. The surface area of this object is four pi times radius squared. For 10 points, name these round objects which consist of all the points equidistant from a given point.
These objects give their name to the harmonic functions which give the angular part of solutions to Laplace's equation.
