A tool for computing the hyperbolic tangent of a given input, this function, derived from calculus, represents the ratio of the hyperbolic sine to the hyperbolic cosine. For example, an input of 0 yields an output of 0, while larger magnitude inputs asymptotically approach 1.
This mathematical function finds widespread application in various fields. In physics, it models phenomena such as magnetic fields and the velocity of waves. Electrical engineering utilizes it in circuit analysis, while computer science leverages it in machine learning algorithms like neural networks for activation functions. The ability to readily compute this function has become increasingly important with the rise of computational modeling and simulation.
