Frequently Asked Questions
What is hyperbolic tangent?
Hyperbolic tangent (tanh) is the ratio sinh(x) / cosh(x), analogous to how ordinary tangent relates to sine and cosine.
What range does tanh fall in?
Unlike ordinary tangent, tanh always produces a value strictly between -1 and 1, approaching but never reaching those limits as x moves toward positive or negative infinity.
Where is tanh used?
Tanh is a common activation function in neural networks, since its smooth S-shaped curve and bounded output make it useful for squashing values into a fixed range.
