ee.Number.sin

  • The sin() method computes the sine of an input number given in radians.

  • It takes a single argument, the input number (angle in radians), and returns a number representing the sine.

 Computes the sine of the input in radians.

UsageReturns
Number.sin()Number
ArgumentTypeDetails
this: inputNumberThe input value.

Examples

Code Editor (JavaScript)

// Input angle in radians.
print('Sine of 0', ee.Number(0).sin());  // 0
print('Sine of π/2', ee.Number(Math.PI/2).sin());  // 1
print('Sine of 3π/2', ee.Number(3*Math.PI/2).sin());  // -1

// Convert degrees to radians.
var degrees = 45;
var radians = degrees * (Math.PI/180);
print('Sine of 45 degrees', ee.Number(radians).sin());  // 0.707106781
