The cosh node returns the hyperbolic cosine of the value of its child-node.

• Minimum number of child-nodes: 1
• Maximum number of child-nodes: 1
• Valid input range: no constraints, but must be in radians

The cosh node returns the hyperbolic cosine of the angle (in radians) represented by its child-node's value.

value = e^x + e^-x, where x = value₁
