print('Length from origin to point (0,0)', ee.Number(0).hypot(0)); // 0
print('Length from origin to point (3,0)', ee.Number(3).hypot(0)); // 3
print('Length from origin to point (3,4)', ee.Number(3).hypot(4)); // 5
print('Length from origin to point (-3,4)', ee.Number(-3).hypot(4)); // 5
print('Length from origin to point (-3,-4)', ee.Number(-3).hypot(-4)); // 5
