// Examples using the sin() math function.
print(ee.Number(-Math.PI).sin());  // Almost 0.0
print(ee.Number(0).sin());  // 0
print(ee.Number(Math.PI / 2.0).sin());  // 1
print(ee.Number(Math.PI).sin());  // Almost 0.0

// Define a sequence from -2pi to +2pi in 50 increments.
var start = -2 * Math.PI;
var end = 2 * Math.PI;
var points = ee.List.sequence(start, end, null, 50);

// Evaluate the sin() function for each value in the `points` sequence.
var values = points.map(function(val) {
  return ee.Number(val).sin();
});

// Evaluate and plot the equations defined above.
var chart = ui.Chart.array.values(values, 0, points)
