## 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.

### See Also

Trigonometric and hyperbolic functions in R.

### Examples

    cot(1+1i)       # 0.2176 - 0.8680i
    csc(1+1i)       # 0.6215 - 0.3039i
    sec(1+1i)       # 0.4983 + 0.5911i
    acot(1+1i)      # 0.5536 - 0.4024i
    acsc(1+1i)      # 0.4523 - 0.5306i
    asec(1+1i)      # 1.1185 + 0.5306i
