Still working on this.

Found some formulas that are helping in my confusion.

I thought converting from Radian to Degrees was simple enough, divide by PI mult by 180 and so forth. But that is not working.

So I went back to the old trig book and refreshed myself on (at least I tried to) radians and things.

My calculator shows:
COSINE of 2 in DEGREES = 0.99939082

COSINE of 2 in RADIANS = -0.41614683

Now if I want to convert Radians to degrees I do this:
COSINE of (2 / 57.29577951) in RADIANS = 0.99939082

My question is... How do I go the other way?
COSINE of 2 ??? in DEGREES = -0.41614683
