Th () function is a hyperbolic tangent function, which can be expressed as: th(x)=sinh(x)/cosh(x), and x=0.5 is known. According to the definition of hyperbolic tangent function, the value of th(0.5) can be calculated as: th(0.5) = Sinh (0.5)/Cosh (0.5).

Hyperbolic tangent function is a kind of hyperbolic function. Hyperbolic tangent function is generally written as tanh in mathematical language, and can also be abbreviated as th.
