Examples
Code Editor (JavaScript)
// Input angle in radians.
print('Cosine of 0', ee.Number(0).cos()); // 1
print('Cosine of π/2', ee.Number(Math.PI/2).cos()); // 0 (nearly)
print('Cosine of π', ee.Number(Math.PI).cos()); // -1
// Convert degrees to radians.
var degrees = 45;
var radians = degrees * (Math.PI/180);
print('Cosine of 45 degrees', ee.Number(radians).cos()); // 0.707106781
