stupid math terminology / notations

Postby TerraFrost » Wed Mar 01, 2006 11:37 pm

Since I've been a UT student, there have been a few terms and notations that I found to be, quite simply, unnecessarily confussing. Oddly enough, I've never encountered the terms at UT - just the notations. But, anyway, here's my list of stupid math terminology and notations. Feel free to add to it :):

  • radix-n: means the same thing as base-n.
  • residue: the answer to the equation a mod n. since there are an infinite number of answers (a+q*n, for any integer q, be it positive or negative), the set of all answers is known as the residue class. the smallest positive answer is known as the common residue.
  • ab (mod n): this is the same thing as saying a mod n = b mod n
  • Image: to translate that into words, 'a is a turing machine that is mapping reducable to a turing machine b'. to turn that into words that actually mean something, 'b can be used to solve a'.

:D :D What about the word "respect" :); It is used very often but it dows not mean anaything :)
And one more word group: "but at most finetly many terms are nonzero " , God! :) It is too confusing for me :) when dealing with sequences :D
