This mathematician names a formula that gives the Taylor series of the inverse of an analytic function, given the original Taylor series coefficients for the function.
This mathematician names a formula that gives the Taylor series of the inverse of an analytic function, given the original Taylor series coefficients for the function. In his solution to the tautochrone problem, he showed minimizing a certain variational integral is equivalent to solving a differential equation named for him (*) and Euler. This mathematician proved that every natural number can be written as the sum of four squares, and constrained optimization problems employ his namesake "multipliers" symbolized lambda. For 10 points, name this mathematician whose namesake "points" are relative stationary points for a third body in a two-body gravitational system.
