# 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

Find more information about changing properties here: linkFunction

*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

Unit

*type: Select from the list*

Select whether the trigonometric function is in degrees or radians.

Select one of those presets:

Unit is in radians

Unit is in degrees

**Radians**Unit is in radians

**Degrees**Unit is in degrees

Caption

*type: Word or phrase*

The name of the object in the project. This name must not contain '.' or '$' characters.

Every object has the Caption property. This property is very important, because it is the name by which Polybench recognizes this object.

It is allowed to give multiple objects the same name, as long as the objects are of the same type. In that case, a reference to this caption includes all the objects with the same caption.

In Polybench, every object can be addressed by an Address specifier, which starts with the dollar sign, for example:

It is allowed to give multiple objects the same name, as long as the objects are of the same type. In that case, a reference to this caption includes all the objects with the same caption.

In Polybench, every object can be addressed by an Address specifier, which starts with the dollar sign, for example:

*$My Page.My Object*. 'My Page' would be the Caption of a page, and 'My Object' the Caption of an object on that page.Documentation

*type: See description*

Optional documentation of this object.

It is good practice to write in short notes why you have used this object, and why its properties are set the way they are set. If this object is an operator, the Documentation text is displayed below the operator symbol.
