I HAVE A MAJOR ANNOUNCEMENT
I have hereby nominate WaterIsPoison for super-awesome status. He just AIMed me while sitting in a college CS lecture. That's 21 slacking-off points and a disrespect bonus of +2.
Such things were not possible in my days in college, because wi-fi was not yet widespread. In my senior year, I worked for the IT department, and helped wire most of campus as a wireless hots pot, but that capability had not yet been implemented in most lecture buildings when I graduated.

I need to get on that.
Or I could save up for a laptop...
Even in the lame math class, that sadly, I'm in...
If only I turned my work in on time! I could be in Algebra!
But it wasn't a "real" one, I don't think. It was like something for the magnet students or whatever.
Identities are incomparably harder when you don't have a calculator to save the tables in. It's all memorization now. Mind you, knowing the identities off by heart is an important skill, but the learning curve sucks. :P
That sounds familiar.
(I hope this isn't like when I asked what "CG" stood for in BitTorrents...)
tanx = (sinx/cosx) is a fundamental trig identity. As well,
.5 = 1/2 is a fundamental algebraic identity.
They get a LOT more complex as you start deriving more and more identities to "simplify" the process
A: The magnitude of the mouse multiplied by the magnitude of the elephant multiplied by the sine of the angle between the two.
Q: What do you get when you cross an elephant with a mountain climber?
A: Nothing. The mountain climber is a scalar.
A: A square-root-of-negative-one-Pod.
