    Identifying a convergent/divergent series

    Was watching a few videos and came across this: If <a href="http://www.codecogs.com/eqnedit.php?latex=\lim_{n \to \infty} a_{n} \neq 0" target="_blank"><img src="http://latex.codecogs.com/gif.latex?\lim_{n \to \infty} a_{n} \neq 0" title="\lim_{n \to \infty} a_{n} \neq 0" /></a> the series is...

    Value of the argument

    According to the Terry Lee book (Page 36), it reads: "The angle Theta is called the argument, -pi < Theta <= pi or -180 < Theta <= 180" I don't understand why arg(z) can't equal to -pi?

    Majoring in Physiology - MedSci

    I know it is still early days but according to the website, it is recommended I pick up junior units of physics in first year (I'm obliged to anyway). Although, I'm taking PHYS 1002 and PHYS 1004 since I don't really require university knowledge for physics (Just year 12) and I don't know...

    PHYS 1001 & 1004 opinions?

    Hey guys. So I'm planning on bridging Physics and doing PHYS 1001 and 1004. Can anyone offer opinions of these units regarding things like course difficulty, how interesting the content actually is and such? How much difficulty will I face having bridged physics? A lot? And another...

    Units of study scaling

    After looking through the list of units of study I was wondering, does studying a unit such as Chemistry 1A "disadvantage" an individual against a student doing say Chemistry 1A Advanced as a result of it's supposedly high scaling? Much like for example doing Standard english in the HSC...

    General discussion of PDHPE

    After being on the Bored of Studies site for a moderately long time, it has come to my attention that PDHPE has been silent throughout most of the year except during times such as the HSC trials and the HSC exam. In an attempt to stimulate activity within this forum, I want to make threads to...

    Chemistry Questions

    Quick Question What qualitative information does the following chemical equation give you? N2 (g) + 3H2 (g) -> 2NH3 (g) I'm not sure what it means by "Qualitative"? Do you just explain what elements are present and how they react to form ammonia? Thanks!

    Chemical reactions - Conservation of mass

    Upon reading, I came across this and don't understand how mass is conserved in case 2 and 5, whilst in case 1,3,4,6, mass is not conserved. (The cases refer to the common ways of deciding that a chemical reaction has occurred) Case 1: If a gas is evolved, for e.g. zinc granules dropped into...

    Chemical reactions - Number of atoms

    In Conquering Chemistry I came across something unclear in my opinion and I just need some clarification. I quote: "The number of atoms of each type is conserved. For example in case 5 above, the number of chlorine atoms in the products is equal to the number in the reactants; similarly for...

    Physical applications of calculus - Rates of change

    A lamp is 6m directly above a straight path. A man 2m tall walks along the path away from the light at a constant speed of 1m/s. At what speed is the end of his shadow moving along the path? At what speed is the length of his shadow increasing? I've drawn the diagram correctly (I've checked the...
