Mathematical Treasure: Emerson's Doctrine of Fluxions

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

William Emerson (1701-1782) was an eccentric English mathematician. He was a small land holder and tried his hand as a school teacher but failed. He retired early from the world in general and devoted his time to music and the writing of mathematics and other scientific works. While Emerson may have failed as a teacher of mathematics, he was a prolific and knowledgeable author of mathematics texts. Eventually he published over a dozen books. His Doctrine of Fluxions (1743) was very popular in England and was used for many years as a basic calculus textbook.

The “Preface” heaps praise on fluxions and their mathematical power:

The first page of the text supplies basic definitions:

Computational instruction starts on page 5:

Emerson would publish a ten-volume series on mathematics titled Cyclomathesis in 1770. This publication is also featured in Convergence's Mathematical Treasures.
