Examples

Code Editor (JavaScript)

var π = Math.PI;
print(ee.Array([-π]).sin());  // [Almost zero]
print(ee.Array([-π / 2.0]).sin());  // [-1]
print(ee.Array([0]).sin());  // [0]
print(ee.Array([π / 2.0]).sin());  // [1]
print(ee.Array([π]).sin());  // [Almost zero]

var start = -π;
var end = π;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.sin();

// Plot sin() defined above.
var chart = ui.Chart.array.values(values, 0, points)
    .setOptions({
