Fundamenta nova theoriae functionum ellipticarum

One of the most exciting moments of my life was when, after computing several of these series, I went down to our mathematical library and found some of them in Jacobi's "Fundamenta nova theoriae..."[3], with the same coefficients down to the last decimal digit!

In mathematics, Fundamenta nova theoriae functionum ellipticarum[1] (new foundations of the theory of elliptic functions) is a book on Jacobi elliptic functions by Carl Gustav Jacob Jacobi.[2] The book was first published in 1829, and has been reprinted in volume 1 of his collected works and on several later occasions. The book introduces Jacobi elliptic functions and the Jacobi triple product identity.
