## Transcendental Function

an analytic function that is not algebraic. Simple examples of transcendental functions are exponential functions, trigonometric functions, and logarithmic functions.

If transcendental functions are treated as functions of a complex variable, a characteristic feature of a transcendental function is the existence of at least one singularity other than poles and branch points of finite order (seeSINGULAR POINT). For example, e2, cos z, and sin z have the essential singularity z = ∞, and In z has branch points of infinite order at z = 0 and z = ∞.

The foundations of the general theory of transcendental functions are provided by the theory of analytic functions. Special transcendental functions are studied in the corresponding disciplines—for example, the theory of hypergeometric functions, the theory of elliptic functions, or the theory of Bessel functions.
