yes, they're in radians. they are either float or double trigonometric functions, and when you stick a constant in there, a7 assumes you are calling the float/double version. if you used vars you'd get the var version, which uses degrees. or, if you want to make sure it uses degrees call sinv, cosv, tanv, asinv, acosv, atanv.

i think it's because radians are the standard unit of measure for angles, so conitec wanted to move to using those without losing backwards compatibility with those using degrees.
