sin(2*pi/65537) = 0.0001
cos(2*pi/65537) = 1.0000

The answer will depend on whether the angles are measured in degrees or radians. That information is not provided and so the question cannot be answered.
Cosine(30) = sqrt(3)/2
(1+sqrt(3))/(2 sqrt(2))

It doesn't really. Depending on the exact value of the argument, the cosine function can give both positive and negative results, for a negative argument. As to "why" the sine, or cosine, functions have certain values, just look at the function definition. Take points on a unit circle. The sine represents the y-coordinate for any point on the circle, while the cosine represents the x-coordinate for such a point. (There are also other ways to define the sine and the cosine functions.)
Cosine(30) = sqrt(3)/2
Mario's cosine also the exact opposite of Mario.
(1+sqrt(3))/(2 sqrt(2))
Yes, the Pythagorean theorem gives the exact measurements always. It can be backed up by proofs and sin, cosine, etc.

mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30
