FAQ About Leonhard Euler

How did Euler influence modern mathematical notation?
Euler introduced much of the mathematical notation in use today. For instance, he popularized the use of the notation f(x) for a function, the letter e for the base of natural logarithms, the Greek letter π to denote the ratio of the circumference of a circle to its diameter, and the symbol Σ for summation. His conventions greatly standardized and simplified mathematical expressions.
