====== Description ====== The tanh node returns the hyperbolic tangent of the value of its child-node. ====== Constraints ====== * Minimum number of child-nodes: 1 * Maximum number of child-nodes: 1 * Valid input range: no constraints, but must be in radians ====== Calculus ====== The tanh node returns the hyperbolic tangent of the angle (in radians) represented by its child-node's value. value={sinh(value_1)}/{cosh(value_1)}
