# Trigonometric Function

## Overview

This operator offers trigonometric functions and some inverse trigonometric functions (cyclometric functions).Note that some of the functions have restricted input values, due to the mathematical properties of some of the trigonometric functions.

## Operator ports

**Input S**: Floating point values

**Output tri(S)**: Floating point values

## Properties

*type: Select from the list*

The function of this operator, which is any of the listed trigonometric functions.

Select one of those presets:

Sine (opposite / hypotenuse)

Cosine (adjacent / hypotenuse)

Tangent (opposite / adjacent)

Cotangent (adjacent / opposite)

Secant (hypotenuse / adjacent)

Cosecant (hypotenuse / opposite)

Inverse sine, so that y = arcsin x, where x = sin y and -1 <= x <= 1

Inverse cosine, so that y = arccos x, where x = cos y and -1 <= x <= 1

Inverse tangent, so that y = arctan x, where x = tan y

Inverse tangent, so that y = arccot x, x = cot y

**sin**Sine (opposite / hypotenuse)

**cos**Cosine (adjacent / hypotenuse)

**tan**Tangent (opposite / adjacent)

**cot**Cotangent (adjacent / opposite)

**sec**Secant (hypotenuse / adjacent)

**csc**Cosecant (hypotenuse / opposite)

**arcsin**Inverse sine, so that y = arcsin x, where x = sin y and -1 <= x <= 1

**arccos**Inverse cosine, so that y = arccos x, where x = cos y and -1 <= x <= 1

**arctan**Inverse tangent, so that y = arctan x, where x = tan y

**arccot**Inverse tangent, so that y = arccot x, x = cot y
