// Input angle in radians.
print('Hyperbolic tangent of -5', ee.Number(-5).tanh()); // -0.999909204
print('Hyperbolic tangent of -1', ee.Number(-1).tanh()); // -0.761594155
print('Hyperbolic tangent of 0', ee.Number(0).tanh()); // 0
print('Hyperbolic tangent of 1', ee.Number(1).tanh()); // 0.761594155
print('Hyperbolic tangent of 5', ee.Number(5).tanh()); // 0.999909204
// Convert degrees to radians.
var degrees = 45;
var radians = degrees * (Math.PI/180);
print('Hyperbolic tangent of 45 degrees',
ee.Number(radians).tanh()); // 0.655794202
