Contoh
Code Editor (JavaScript)
print(ee.Array([-5]).tanh()); // [~ -1]
print(ee.Array([0]).tanh()); // [0]
print(ee.Array([5]).tanh()); // [~ 1]
var start = -5;
var end = 5;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.tanh();
// Plot tanh() defined above.
var chart = ui.Chart.array.values(values, 0, points)
.setOptions({
viewWindow: {min: start, max: end},

{v: start},
{v: 0},
{v: end}]
