trigonometric functions in attribute draw:formula (19.171, part1 ODF1.2) specify angle in degree but widely implemented as radian

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 .
