Hyperbolic functions were introduced in the 1760s independently by Vincenzo Riccati and Johann Heinrich Lambert. Hyperbolic functions occur in the solutions of many linear differential equations. The tanh function operates element-wise on arrays. Basic hyperbolic functions are the hyperbolic sine "sinh" and the hyperbolic cosine "cosh". Here is a tanh graph formula which helps to calculate Hyperbolic Tangent. To get the value of tanh x, just divide sinh x by cosh x.
Tanh graph formula is used to represent the graph for minimum and maximum values. You can refer the online calculator provided above to find the hyperbolic tangent function graph.
