§4.1 Special Notation

(For other notation see Notation for the Special Functions.)

It is assumed the user is familiar with the definitions and properties of elementary functions of real arguments x . The main purpose of the present chapter is to extend these definitions and properties to complex arguments z .

The main functions treated in this chapter are the logarithm ln ⁡ z , Ln ⁡ z ; the exponential exp ⁡ z , ez ; the circular trigonometric (or just trigonometric) functions sin ⁡ z , cos ⁡ z , tan ⁡ z , csc ⁡ z , sec ⁡ z , cot ⁡ z ; the inverse trigonometric functions arcsin ⁡ z , Arcsin ⁡ z , etc.; the hyperbolic trigonometric (or just hyperbolic) functions sinh ⁡ z , cosh ⁡ z , tanh ⁡ z , csch ⁡ z , sech ⁡ z , coth ⁡ z ; the inverse hyperbolic functions arcsinh ⁡ z , Arcsinh ⁡ z , etc.

Sometimes in the literature the meanings of ln and Ln are interchanged; similarly for arcsin ⁡ z and Arcsin ⁡ z , etc. Sometimes “arc” is replaced by the index “ − 1 ”, e.g. sin − 1 ⁡ z for arcsin ⁡ z and Sin − 1 ⁡ z for Arcsin ⁡ z .
