Query: Nested Coordinate Systems in Geometric Algebra   A nested coordinate system is a reassigning of independent variables to take
advantage of geometric or symmetry properties of a particular application.
Polar, cylindrical and spherical coordinate systems are primary examples of
such a regrouping that have proved their importance in the separation of
variables method for solving partial differential equations. Geometric algebra
offers powerful complimentary algebraic tools that are unavailable in other
treatments.
