Trigonometric functions¶

The <input> and <output> tags of every module on this page additionally accept the attributes common to all analysis modules.

acos¶

Calculates the inverse cosine of a single input element-wise and writes the resulting angle to a single output buffer. This module will write as many values as there are values in the input buffer. The angle is returned in radians unless degrees are requested using the deg attribute.

<acos deg="BOOLEAN">
    <input as="value">BUFFER</input>
    <output as="acos">BUFFER</output>
</acos>

Attributes

deg: Return the angle in degrees instead of radians.; added in 1.2 optional, boolean, default: false

Inputs

`as`	Count	`as` required	Allowed types
`value`	exactly one	no	`buffer`, `value`

Outputs

`as`	Count	`as` required
`acos`	exactly one	no

asin¶

Calculates the inverse sine of a single input element-wise and writes the resulting angle to a single output buffer. This module will write as many values as there are values in the input buffer. The angle is returned in radians unless degrees are requested using the deg attribute.

<asin deg="BOOLEAN">
    <input as="value">BUFFER</input>
    <output as="asin">BUFFER</output>
</asin>

Attributes

deg: Return the angle in degrees instead of radians.; added in 1.2 optional, boolean, default: false

Inputs

`as`	Count	`as` required	Allowed types
`value`	exactly one	no	`buffer`, `value`

Outputs

`as`	Count	`as` required
`asin`	exactly one	no

atan¶

Calculates the inverse tangent of a single input element-wise and writes the resulting angle to a single output buffer. This module will write as many values as there are values in the input buffer. The angle is returned in radians unless degrees are requested using the deg attribute.

<atan deg="BOOLEAN">
    <input as="value">BUFFER</input>
    <output as="atan">BUFFER</output>
</atan>

Attributes

deg: Return the angle in degrees instead of radians.; added in 1.2 optional, boolean, default: false

Inputs

`as`	Count	`as` required	Allowed types
`value`	exactly one	no	`buffer`, `value`

Outputs

`as`	Count	`as` required

atan2¶

Calculates the two-argument variant of the inverse tangent (corresponding to atan(y/x), see Wikipedia for an explanation) element-wise and writes it to a single output buffer. The angle is returned in radians unless degrees are requested using the deg attribute. Like the other element-wise modules with several inputs, the output has the length of the longest input and a shorter input repeats its last value; any empty input yields an empty output.

<atan2 deg="BOOLEAN">
    <input as="y">BUFFER</input>
    <input as="x">BUFFER</input>
    <output as="atan2">BUFFER</output>
</atan2>

`as`	Count	`as` required
`atan2`	exactly one	no
