Contoh

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
