The asin node returns the arc sine of the value of its child-node.

• Minimum number of child-nodes: 1
• Maximum number of child-nodes: 1
• Valid input range: -1. to +1.
• Output range: -/2 to +/2 (radians)

The asin node's value is the arc sine, in radians, of the value of its child-node. If the input value is out of range then the acos node returns an ERROR value.

For valid value₁:

value = sin^-1(value₁)

For invalid value₁:

value = ERROR
