Change the text "degree" to "radian".

Current text:
sin returns the trigonometric sine of n, where n is an angle specified in degrees
cos returns the trigonometric cosine of n, where n is an angle specified in degrees
tan returns the trigonometric tangent of n, where n is an angle specified in degrees
atan returns the arc tangent of n in degrees
atan2(x,y) returns the angle in degrees of the <..> with the x-axis

Proposed text:
sin returns the trigonometric sine of n, where n is an angle specified in radians
cos returns the trigonometric cosine of n, where n is an angle specified in radians
tan returns the trigonometric tangent of n, where n is an angle specified in radians
atan returns the arc tangent of n in radians
atan2<..> returns the angle in radians of the vector (x,y) with the x-axis

I have skipped "(x,y)" here, because that is in issue OFFICE-3822.

#### Description

For the trigonometric functions sin, cos, tan, atan, and atan2 the angle is specified to be in degree. But the applications Apache OpenOffice, Symphony, LibreOffice, Calligra Stage, PowerPoint Preview 2013 have implemented it to be in radian.

Does anyone know an application, that has implemented the angle to be in degree?
If not, I suggest to change it in ODF1.2 Errata.
