// Input angle in radians.
print('Hyperbolic cosine of -5', ee.Number(-5).cosh()); // 74.209948524
print('Hyperbolic cosine of -1', ee.Number(-1).cosh()); // 1.543080634
print('Hyperbolic cosine of 0', ee.Number(0).cosh()); // 1
print('Hyperbolic cosine of 1', ee.Number(1).cosh()); // 1.543080634
print('Hyperbolic cosine of 5', ee.Number(5).cosh()); // 74.209948524
// Convert degrees to radians.
var degrees = 45;
var radians = degrees * (Math.PI/180);
print('Hyperbolic cosine of 45 degrees',
ee.Number(radians).cosh()); // 1.324609089
