Detail: He lived 1707 to 1783 and invented Euler's formula, Euler number, and Euler constant. He studied incompressible non-rotating non-viscous fluid flows {potential flow}. He studied non-homogeneous nth order differential equations, partial-fractions method, explicit and implicit functions, networks, harmonic and divergent series, hypergeometric functions, natural logarithms, partial derivatives, multiple integrals, calculus of variations, finite-differences method, and gamma and beta functions.
First-order equations can be exact differentials. Newton's laws can depend on a maximizing-minimizing principle {principle of stationary action} {stationary action principle} {Euler-Lagrange equations}.
