var π = Math.PI; print(ee.Array([-π]).cos()); // [-1] print(ee.Array([-π / 2.0]).cos()); // [Almost zero] print(ee.Array([0]).cos()); // [1] print(ee.Array([π / 2.0]).cos()); // [Almost zero] print(ee.Array([π]).cos()); // [-1] var start = -π; var end = π; var points = ee.Array(ee.List.sequence(start, end, null, 50)); var values = points.cos(); // Plot cos() defined above. var chart = ui.Chart.array.values(values, 0, points) .setOptions({ viewWindow: {min: start, max: end}, hAxis: { title: 'x', viewWindowMode: 'maximized', ticks: [ {v: start, f: '-π'}, {v: 0, f: 0}, {v: end, f: 'π'}] }, vAxis: { title: 'cos(x)', ticks: [ {v: -1, f: -1}, {v: 0, f: 0}, {v: 1, f: 1}] }, lineWidth: 1, pointSize: 0, }); print(chart);
