Cool, just like factorials!

Ah..so ie. sin(45) = 0.707106781..., this would be sine?

AND

arcsine (0.707106781...) = 45?

Well, just really anything in particular.

ie. Prove that if 25 is subtracted from the square of an odd integer greater than 5, the resulting number is always divisible by 8.

Well, for binomials, its really easier to use the synthetic division; as its less complex.

What's that?

Also, I've read somewhere on the Theory of Relativity, and faster than light travel.

Apparently travelling faster than light is imaginary as well:D

When someone says "A is inversely proportional to B, it means A=k/B", where k is some proportionality constant.

Or 2 inverse is 1/2, or 0.5, or 2^-1 = 1/2.

Why is that sin inverse, although written as sin^-1 is not 1/sin?

Likewise for cosine and tangent.

Could it be that the make-up of atoms and other sub-atomic particles are actually like fractals? That is, a pattern going on for infinity?

I'm finding it hard to do geometry proofs.

I can handle analytical proofs, but the vector and deductive proofs are way over my head...

How do you guys approach these types of proof?
