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)
