I got -252, but only after fully expanding (a-3)^4 and then multiplying the terms in a^2 by (-4a) and the term in a^3 by 3, and then added them.
I hope there's a faster way than this.
Find the coefficient of a3 in the expansion of (3 − 4a)(a − 3)^4
Can we just write out the general term for (a-3)^4 and multiply by (3-4a), and collect like terms?
Most of the hard binomial questions are usually identities. The rest of it isn't so bad usually. You're best off either focusing on other MX1 topics (as not all 70 marks will be on binomial, as has been said), or just focus on the easier parts of binomial minus the identities. The 2nd strategy...
BOS definition: "Identify issues and provide points for and/or against"
How do we do that for essay questions?
E.g. If the question asks to e.g. "Discuss the how connections to place can impact one's sense of belonging" should we include how connections can improve AND worsen one's sense of...
Apparition LOL, that's actually my fave one :) It relates to almost nothing though, so I'm not going to look into it too much. I really like the 4 poem detailed study + 2 quotes from remaining idea.
LOVE the speeches in Mod B lol (except Deane and Pearson)
There are 9 (!!!) poems altogether, and I seriously hope they don't specify. One of our teachers said that Donne's poems can be treated as a single text, so does this mean that they won't specify specific poems (just like they can't specify Act 2 Scene 1 of As You Like It for AOS without...
LOL same problem here! Eng and eco are by far my weakest, but I keep doing maths because the short term satisfaction gained from maths study is too tempting.
What? Unless it is specified, I doubt you need to write the temperatures out for EVERY equation that's needed. I didn't lose any marks in the trials for not including temperatures where they weren't specified.
You've got me worried though LOL.
