radians() : Convert Degrees to Radians

Convert an angle from degrees to radians.

On this page

Signature

radians(degrees)

Parameters

Parameter Type Required Description
degrees Number Yes The angle in degrees

Returns

Type: Double

The angle in radians.

Examples

Convert Common Angles

<p>30° = {{format(radians(30), '0.000')}} radians</p>
<p>45° = {{format(radians(45), '0.000')}} radians</p>
<p>90° = {{format(radians(90), '0.000')}} radians</p>
<p>180° = {{format(radians(180), '0.000')}} radians</p>

Output:

<p>30° = 0.524 radians</p>
<p>45° = 0.785 radians</p>
<p>90° = 1.571 radians</p>
<p>180° = 3.142 radians</p>

Use with Trigonometric Functions

<p>sin(30°) = {{format(sin(radians(30)), '0.000')}}</p>
<p>cos(60°) = {{format(cos(radians(60)), '0.000')}}</p>
<p>tan(45°) = {{format(tan(radians(45)), '0.000')}}</p>

Output:

<p>sin(30°) = 0.500</p>
<p>cos(60°) = 0.500</p>
<p>tan(45°) = 1.000</p>

Calculate Circular Position

<p>X: {{format(model.radius * cos(radians(model.angle)), '0.00')}}</p>
<p>Y: {{format(model.radius * sin(radians(model.angle)), '0.00')}}</p>

Data:

doc.Params["model"] = new {
    radius = 10,
    angle = 45  // degrees
};

Output:

<p>X: 7.07</p>
<p>Y: 7.07</p>

Notes

  • Converts degrees to radians
  • Formula: radians = degrees × (Ï€/180)
  • Inverse of degrees() function
  • Required for trigonometric functions (sin, cos, tan)
  • 360° = 2Ï€ radians, 180° = Ï€ radians
