Description

• 

In the Simple Units environment, the diff function differentiates an expression a with respect to a name x that can have a unit.  The result is the derivative of a with respect to x; its unit is the unit of a divided by the unit of x.

• 

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 function diff.

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 unit and then enter the unit.

When you edit a unit, double brackets appear around it.
