Abstract
For any Liouville number
$\alpha $
, all of the following are transcendental numbers:
${e}^\alpha $
,
$\log _{e}\alpha $
,
$\sin \alpha $
,
$\cos \alpha $
,
$\tan \alpha $
,
$\sinh \alpha $
,
$\cosh \alpha $
,
$\tanh \alpha $
,
$\arcsin \alpha $
and the inverse functions evaluated at
$\alpha $
of the listed trigonometric and hyperbolic functions, noting that wherever multiple values are involved, every such value is transcendental. This remains true if ‘Liouville number’ is replaced by ‘U-number’, where U is one of Mahler’s classes of transcendental numbers.
