Hi

( 360 /  7 ) cos
while
( 360 / 7) degreeCos raises an error.

Is this simply because we should add

Fraction>>degreeCos
	"Answer the cosine of the receiver taken as an angle in degrees."

	^ self degreesToRadians cos

Fraction>>degreeSin
	"Answer the sine of the receiver taken as an angle in degrees."

	^ self degreesToRadians sin


Would it be better to put it in Number?
Any expert to help here?

I was always good in math but never in arithmetics....;)
