    What Defines a Step in a Markov System or Process?

    It's actually just a general question about the MS/P (Markov System &/or Process) (I'm not sure what to call it). In the MS/P, is 1 "step" the same as 1 day(or unit), or is the amount of day(s) (or unit(s)) decided by the programmer/user/instructor/etc.. I know this isn't "homework", but it's...

    What are subsets and proper subsets in set theory?

    :smile: Indeed, I was wondering what the applications of set theory are. I had a talk with my Data Structures & Algorithms I professor & she showed me a few ways it helps. Thanks.

    What are subsets and proper subsets in set theory?

    Why does "Set theory" exist? Is there actually a use for Set theory? I understand why Algebra, Calculus, Trig, Physics, etc.. exist. Does anyone ever use it at their job (besides at some type of school).

    Showing work (Perfectly Elastic Collision)

    Homework Statement Two pool balls hit head on. V(1) = 2.0 m/s west, V(2) = 5 m/s east. Mass is the same for each ball. Homework Equations The Attempt at a Solution m(1)*(-2m/s)^2 + m(2)*(5m/s)^2 =? no idea...I just know that each ball should be going the same speed and direction as the...
