This paper begins with an expression of the trapezoid rule for "formal mechanical quadrature." Euler also sums the first ten terms of ζ(2) to get 1.549768 and gives an expression for the error term. Then he determines the sum of the first million terms of the harmonic series to be 14.392669.

De Indorum Anno Solari Astronomico, Leonhard Euler

All Works by Eneström Number

This work is an appendix following two other appendices in a book by Euler's friend and St. Petersbrg Academy colleague T. S. Bayer, Historia regni Graecorum Bactriani (History of the Bactrian kingdom of the Greeks). The original appendices were written by a Danish missionary in Tranquebar, C. T. Walther ("The Indian Doctrine of Time," pp. 145-190), and by Bayer himself, based on his correspondence with Walther and other Tranquebar missionaries ("Supplement to the Indian Doctrine of Time," pp. 191-200). Euler's contribution appears immediately after these.

De Formis Radicum Aequationum Cuiusque Ordinis Coniectatio, Leonhard Euler Dec 1737

De Formis Radicum Aequationum Cuiusque Ordinis Coniectatio, Leonhard Euler

All Works by Eneström Number

For an equation of degree n, Euler wants to define a "resolvent equation" of degree n-1 whose roots are related to the roots of the original equation. Thus, by solving the resolvent one can solve the original equation. In sections 2 to 7 he works this out for quadratic, cubic, and biquadratic equations. In section 8 Euler says that he wants to try the same approach for solving the quintic equation and general nth degree equations. In the rest of the paper he tries to figure out in what cases resolvents will work.

Euler first explains his theory of what makes up the atmosphere; the basis of his theory lies in the theory of elasticity of the teacher he had before Johann Bernoulli. He also states without proof a formula for the speed of propagation and derives from it numerical values of the correct order of magnitude for air.
