More Trigonometric Functions

More trigonometric functions not available in R.

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.
