Trigonometric and Hyperbolic Functions in the Simple Units Environment

 

Description

Examples

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 trigonometric or hyperbolic functions is unit-free. With the approach used in this environment, this includes plane angles. An error is returned if the dimension of the argument is not unit-free.

• 

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.

• 

If the argument has a unit of angle, it is converted to a free expression in the call to the corresponding global function.  Therefore, a call to sin(7*deg) returns as sin(7/180*Pi), because 1 degree equals π180 radians.

• 

For other properties, see the global functions in the trig help page.

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.
