Returns the sine of the argument.

The `sin`

function calculates the sine of an angle * z*,
which may be in

`z`

`z`

Returns the cosine of the argument.

The `cos`

function calculates the cosine of an angle * z*,
which may be in

`z`

`z`

Returns the tangent of the argument.

The `tan`

function calculates the tangent of an angle * z*,
which may be in

`z`

For arguments with a large magnitude, the function will begin to lose precision.
`tan`

is undefined at z = p*π/2,
where `p`

is an *integer*,
but the function returns a very large number if * z* is near the undefined value.

Returns the inverse sine of the argument.

The `asin`

function calculates the inverse sine of * z*.
The result may be in

`z`

`sin`

function.
Returns the inverse cosine of the argument.

The `acos`

function calculates the inverse cosine of * z*.
The result may be in

`z`

`cos`

function.
Returns the inverse tangent of the argument.

The `atan`

function calculates the inverse tangent of * z*.
The result may be in

`z`

`tan`

function.
Returns the secant of the argument.

The `sec`

function calculates the secant of an angle * z*,
which may be in

`z`

Returns the cosecant of the argument.

The `csc`

function calculates the cosecant of an angle * z*,
which may be in

`z`

Returns the cotangent of the argument.

The `cot`

function calculates the cotangent of an angle * z*,
which may be in

`z`

Returns the inverse secant of the argument.

The `asec`

function calculates the inverse secant of * z*.
The result may be in

`z`

`sec`

function.
Returns the inverse cosecant of the argument.

The `acsc`

function calculates the inverse cosecant of * z*.
The result may be in

`z`

`csc`

function.
Returns the inverse cotangent of the argument.

The `acot`

function calculates the inverse cotangent of * z*.
The result may be in

`z`

`cot`

function.
The `acot`

function returns a value in the range ]-π/2;π/2] (]-90;90] when calculating in degrees),
which is the most common definition, though some may define it to be in the range ]0;π[.
