Inverse Trigonometric and Hyperbolic Functions in the Simple Units Environment

Description

 • 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.

Examples

Notes:

 – 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 $\mathrm{unit}$ and then enter the unit.
 – When you edit a unit, double brackets appear around it.
