More Trigonometric Functions

Description

More trigonometric functions not available in R.

Usage

cot(z)
csc(z)
sec(z)
acot(z)
acsc(z)
asec(z)

Arguments

z

numeric or complex scalar or vector.

Details

The usual trigonometric cotangens, cosecans, and secans functions and their inverses, computed through the other well known – in R – sine, cosine, and tangens functions.

Value

Result vector of numeric or complex values.

Note

These function names are available in Matlab, that is the reason they have been added to the ‘pracma’ package.
