Inverse Trigonometric and Hyperbolic Functions in the Simple Units Environment
In the Simple Units environment, any verifications of valid dimensions ignore so-called Unit annotations.
In the Simple Units environment, the arguments for the inverse trigonometric or hyperbolic functions must have dimension 1. Otherwise, an error is returned.
Every command in the Simple Units environment that needs to determine whether an expression is valid or not, does so using the Units[TestDimensions] command.
For other properties, see the global functions in the arctrig help page.
To enter a unit in 2-D Math input, select the unit from the appropriate Units palette. If the unit you want is not there, select unit and then enter the unit.
When you edit a unit, double brackets appear around it.
