Name: cos

Type: function

Syntax: the cos of <angle>

Syntax: cos(<angle>)

Summary:

<return|Returns> the cosine of an angle (in <radian|radians>).

Introduced: 1.0

OS: mac, windows, linux, ios, android

Platforms: desktop, server, mobile

Example:

cos(pi)

Example:

the cos of 0

Example:

put cos(the startAngle of graphic 3) into field "Cosine"

Parameters:

angle:

A positive or negative number, or an expression that evaluates to a

number.

Returns:

The <cos> <function> <return|returns> a number between -1 and 1.

Description:

Use the <cos> <function> to find the cosine of an angle.

The <cos> <function> repeats every `2 * pi` <radian|radians>:

`cos(x) = cos(x + 2 * pi)`, for any value of `x`.

The <cos> <function> requires its input to be in <radian|radians>. To

provide an angle in <degree|degrees>, use the following

<custom function>:

function cosInDegrees angleInDegrees

return cos(angleInDegrees * pi / 180)

end cosInDegrees
