Problem of determining missing data for level payment loans  Loan calculation (base)

Variational problem with nonholonomic constraint The correction almost entirely replaces an earlier version (which is not in this list and which had some notational problems). 
Nonholonomic constraint (corrected) 
Quadrature solution of a second order ODE with independent variable absent  ODE, second order
(base) ODE, second order (supplement) 
Problem of determining if ellipses overlap  Overlapping ellipses 
Solution of the second order linear ODE by quadrature  Quadrature solution 
Importation and exportation of quantifiers  Quantifier placement 
Second degree, two dimensional Least Squares Regression  Second degree, 2 dim. LSR 
Reversion of n dimensional power series  Series reversion 
Problem of maximizing the ratio of two functionals The corrected version plugs a hole in the first version posted. About half of the material in the first version is relevant to the corrected approach (and hence the two must be read together).
