radian

radian

The** radian **statement tells Panorama that all angles in trigonometric functions should be calculated using radians rather than degrees.

**Parameters**

No parameters.

**Description**

The *radian* statement doesn’t perform any visible action on its own. However, it tells Panorama that all angles used in subsequent trig functions in the procedure should be calculated using radians, rather than degrees. (Note: Panorama always reverts back to radians after the procedure is finished; radian is the default setting.)
