Mathematical Treasure: Legendre’s Integral Calculus

Exercices de Calcul Intégral by Adrien-Marie Legendre (1752-1833) appeared in three volumes published a bit out of order in 1811 (Vol. I), 1817 (Vol. II), and 1816 (Vol. III). It is considered one of his most important works. The first volume introduces the concept of elliptic functions and integrals, and discusses beta and gamma functions. The other volumes in the series expand on elliptic integrals and their solutions. Below is the title page for the third volume published in 1816:

Within this third volume is a section on methods for the construction of elliptic functions.
