Nutshelled: Binomial expansion of C2 watch

1. Could someone please tell me if any of this pascal's triangle rubbish is necessary from Chatper 5 of C2. Is it just something leading up to the binomial expansion (BE)?

Cause honestly I can do the BE and due to time constraints to cover Chapters 7-11 I really don't want to waste time with it if it's not going to come up in the exam and is just a kinda transitional phenomena to help smooth out the binomial expansion.

P.S. pascal's traingle is nonsensical anyway, how does e.g. 1a^2 + 2ab give you 3a^2b, it's addition of coefficients and multiplication of constants, not simply and plainly 'addition', argh this confusing crap to hell with it.
2. Forget Pascal's Triangle if it isn't helping. Just look at nCr and the manual way of working it out. Much simpler.

So it doesn't come up? I can do the binomial expansion (nCr etc.) part of the chapter, just can't get my head around pascal's triangle.

I am 99.9% it won't come up in the exam. I'm pretty sure it's just a way to help people understand the concept of what you are doing, rather than a method of working x question out.

I thought so too, it's just for transition. Just out of interest, does the binomial expansion get developed later on in the textbook through another topic?

p.s. skipping pascal's triangle, its just dumb and irrelevant lol.

Emm, no it doesn't. The most complex it gets is evaluating (1.000005)^5 and using your newly formed expansion to estimate the answer using a suitable value of x.

I see. Thank you
8. I know the question's already been answered, but just for some more reassurance, don't worry about understanding pascal's triangle! I'm the same as you, can't get my head around it at all. It's the same with me and using long division to divide algebraic expressions :/

But yeah, don't worry and good luck with the rest of C2

Aw I appreciate it. Good luck you to you too ~
