Computes the arcsine in radians of the input.
| Usage | Returns | Number.asin() | Number |
| Argument | Type | Details | this: input | Number | The 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)
Python setup
See the
Python Environment page for information on the Python API and using
geemap for interactive development.
import ee
import geemap.core as geemap
Colab (Python)
# 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)
