TANH (x) |
Location |
Hyper, Hyperbola |
This function is analogous to the tangent (TAN) - the hyperbolic tangent (TANH) is the hyperbolic sine divided by the hyperbolic cosine:
TANH(x) = SINH(x) / COSH(x)
resulting in the following formula (if SINH and COSH are replaced by their definitions):
TANH(x) = (EXP(x) - EXP(-x)) / (EXP(x) + EXP(-x))
CROSS-REFERENCE
ARTANH is the inverse function of TANH, COTH a complementary function to TANH.
