| the algebra 2 test i talked about yesterday was HORRIBLE. Everyone thinks they failed. I'm at the top of my class and i still think i got a 20 on it. The problems were so complicated and weird. |

@gold
yep..
find the inverse of the function: cosѲ/((1/sinѲ)-secѲ
also a bunch of standard deviation crap that i have never heard of.
i don't remember the problems. I was too upset to remember |

we were somehow supposed to "remember" this formula for prior knowledge. I have never even heard of it.
σ = sqrt[Σ(X - μ)² / N] |

σ is standard deviation Σ is summation (fancy word for adding things up) μ I'm pretty sure is an arbitrary constant, I don't remember using it in alg II N I think is a constant that increases with Σ but since he didn't post the limits of Σ I can't really tell |
