There is a Radians (degrees) switch accessible through the Options entry of the main menu.


By default (checked) the unit for angles measurement in the drect  (sin, cos, tan) and inverse trigonometric lines (asin, acos, atan) is radian.

If unchecked, the measurements are in degrees.


The switch can be checked or unchecked only at the beginning of the resolution (at launch or after Files / New).


The state of the switch is recorded when saving a file and in the casiopee.ini iniatization file when closing.
