Elementary function

In mathematics, an elementary function is a function of one variable which is the composition of a finite number of arithmetic operations (+ – × ÷), exponentials, logarithms, constants, trigonometric functions, and solutions of algebraic equations (a generalization of nth roots). In mathematics, an elementary function is a function of one variable which is the composition of a finite number of arithmetic operations (+ – × ÷), exponentials, logarithms, constants, trigonometric functions, and solutions of algebraic equations (a generalization of nth roots). Elementary functions were introduced by Joseph Liouville in a series of papers from 1833 to 1841. An algebraic treatment of elementary functions was started by Joseph Fels Ritt in the 1930s. The elementary functions (of x) include: Some elementary functions, such as roots, logarithms, or inverse trigonometric functions, are not entire functions and may be multivalued.
