In Too Deep

So In my quest to really learn all there is to know about being a TD it has become abundantly clear that math is a very important part of it. The problem I have not a clue when it comes to anything higher than basic algebra (yes, I know i should have paid attention all those years ago in school). So I started teaching myself what I could find that I need to know. So far sin, cos, tan, arcsin, and mod seem to be the really important ones. So the next few posts will most likely focus on what I am learning as I go.

Numbers

Seems the most basic concepts need to come first: the types of numbers that I seem to be dealing with in 3D.

• Rational numbers - Any number than can be written as a fraction - 3/4 = .75
• Irrational numbers - Those that can't be written as a fraction - ∏ and√2

Interesting point I found out is that the float comes from floating point which refers to the decimal point floating back and forth. i.e. .75 x 10 = 7.5 or .75 / 10 = .075. I know I am kind of weird, but I like to know the origins of things like that.
