ee.Number.asin

  • Number.asin() computes the arcsine in radians of the input.

  • The asin() method takes a single numerical input representing the value for which to compute the arcsine.

  • The domain of arcsine is [-1, 1], and inputs outside this range are invalid.

 Computes the arcsine in radians of the input.

UsageReturns

ArgumentTypeDetails
this: inputNumberThe input value.

Examples

Code Editor (JavaScript)

// The domain of arcsine is [-1,1], inputs outside the domain are invalid.
print('Arcsine of -1', ee.Number(-1).asin());  // -1.570796326 (-π/2)
print('Arcsine of 0', ee.Number(0).asin());  // 0
print('Arcsine of 1', ee.Number(1).asin());  // 1.570796326 (π/2)

# The domain of arcsine is [-1,1], inputs outside the domain are invalid.
print('Arcsine of -1:', ee.Number(-1).asin().getInfo())  # -1.570796326 (-π/2)
print('Arcsine of 0:', ee.Number(0).asin().getInfo())  # 0
print('Arcsine of 1:', ee.Number(1).asin().getInfo())  # 1.570796326 (π/2)
