Sin(x + 22) = sin(x)*cos(22) + sin(22)*cos(x)

cos(2x - 7) = cos(2x)*cos(7) + sin(2x)*sin(7)
cos(2x - 7) = [cos^2(x) - sin^2(x)]*cos(7) + 2sin(X)*cos(x)*sin(7)

Somebody sure doesn't like you guys very much. A weak joke. I think the best you can do to start with is graph this relationship. The best I can do is get an answer that is somewhere around 145 degrees. - 61 degrees, - 214 degrees and 255 degrees.

If you are intended to solve this any other way by using the double angle formulas as I started to get above and  sin(x) or cos(x) I would take the 0 and hope to make it up some other way.

The domain is between -360 and plus 360. The range is between +/- 1.

Hope this ; )
