Matrices ain't extension 1 maths lol

At least 1 root is imaginary, so by the conjugate root theorem, it's conjugate is also a root Let z be a purely imaginary root Roots = ib, ib(conj), something sum of roots = -p/3 = real so, ib + ib(conj)+ something = real ib - ib+ something = real something = real So roots are...

Really important... your parents might confiscate all your possessions Mr. Huang!

The desperation..

To do quotient rule the most efficiently is to not memorize the formula (well it is the same thing but you don't need to memorize letters) Here's how I do it.. Step 1: Differentiate top times bottom, MINUS, differentiate bottom times top (-2)(x^2+1) - (2x)(-2x) Step 2: Draw the fraction...

Re: MX2 Integration Marathon Best question in the world

Q1) Apply double-angle formulas for cosine and sine Q2) Notice that the sum is a geometric progression..?

This is possible with powerful peripheral vision

Yes, nitrate ions are the spectator ions. Electron-transfer (2 of them) goes from metal (Fe) to metal ion (Ag+) through a medium (electrolyte - nitrate ions in this case), thus only the metal and metal ions are getting oxidized/reduced.

How are you memorizing the 2000 words? To know whether you have photographic memory or not - after you memorize the 2k words, can you QUICK recall the position of a particular sentence/beginning of paragraph?

Who here plays?

Good question Suppose A is less reactive than B I'd say, since A is less reactive than B, then a displacement reaction will not occur. No need for ionic equation because there isn't any!(?)

Imagine yourself doing the HSC chemistry exam. What you will be doing is actively recalling what you know and applying it. That is... you are testing your knowledge on chemistry So what you want to do is to test yourself 24/7 without the aid of notes. You can read all your notes and memorize...

Revise limiting reagents and species in excess

Read notes/textbook and examine the syllabus. Make sure you can answer every dot point on the syllabus and actually understand it too and to make sure you understand something, make sure you can explain whatever it is to someone clearly and LOGICALLY. E.g., your friend asks to you why a catalyst...
