Mathematical Treasure: l'Hospital's Differential Calculus

Author(s): 
Frank J. Swetz (Pennsylvania State University)

Analyse des Infiniment Petits, published by the Marquis de l’Hospital in 1696, was the first calculus text for a popular audience. L’Hospital (1661-1704), a well-respected mathematician, compiled this book while under the tutelage of Johann Bernoulli, from whom he acquired knowledge of Leibniz’s approach to the calculus. The book adheres to Leibniz’s principles. It includes the technique for dealing with indeterminate expressions now known as l’Hospital’s Rule.
