Computes the arccosine in radians of the input.
| Usage | Returns | Number.acos() | Number |
| Argument | Type | Details | this: input | Number | The input value. |
Examples
Code Editor (JavaScript)
// The domain of arccosine is [-1,1], inputs outside the domain are invalid.
print('Arccosine of -1', ee.Number(-1).acos()); // 3.141592653 (π)
print('Arccosine of 0', ee.Number(0).acos()); // 1.570796326 (π/2)
print('Arccosine of 1', ee.Number(1).acos()); // 0
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 arccosine is [-1,1], inputs outside the domain are invalid.
print('Arccosine of -1:', ee.Number(-1).acos().getInfo()) # 3.141592653 (π)
print('Arccosine of 0:', ee.Number(0).acos().getInfo()) # 1.570796326 (π/2)
print('Arccosine of 1:', ee.Number(1).acos().getInfo()) # 0
