Second Derivative tanh(x) function Calculator

Calculates the second derivative tanh(x) (Tangent Hyperbolic Function).

tanh(x) function is used in the activation function of the neural network.

\(
\normalsize Tangent\ hyperbolic\ function\ \tanh(x)\\
f(x) = \large \tanh(x) = \large \frac {e^{x}-e^{-x}}{e^{x}+e^{-x}}\\
\normalsize f'(x) = 1 - f(x)^{2} \\
\normalsize f''(x) = - 2 f(x) \left\{ 1 - f(x)^{2} \right\} \\\)
