this, unfortunately

It is the only real reason why sciences are seen as 'hard', the science syllabus for HSC (all of them) half of it is utter crap really. Instead of teaching advanced topics in school that are interesting and and good (which are hard to understand etc etc), instead we get socio-economic science where we have to consider why mining can be economically viable or redundant..IN CHEMISTRY.
If the syllabus wasnt so stupid, maybe then I will enjoy the sciences more (I enjoy them when we are doing real things)

No that's my point lol- I do memorise it, I just kept using it wrong haha. I don't even know how to derive that one- maybe I could if I had to but I've never tried it.

Lol Neither.

For trig - I know how to derive Area of triangle (who doesn't?), Sine Rule, Angle between 2 lines - and that's about it. Oh, and the double and compound angle ones.

 

[bleakarcher]

You got it?

yeah

wat up

 

[theind1996]

yeah

What do you reckon?

 

[Fawun]

Too arduous for me. I'd rather just memorise it haha

I memorised cosine rule wrong for 2 tests in a row fml..

I wrote a^2=b^2+c^2+2bccosA lol.

what? isn't that it?

 

[theind1996]

wat up

notsureifsrs.

 

[Shadowdude]

what? isn't that it?

it's minus.

 

[bleakarcher]

Yea it's easy though.

Like there's no challenge. I would have to spend 2x more time on Chem if it was more conceptual as opposed to rote-ing.

lol I'm the other way around.

 

[Sy123]

what? isn't that it?

Its -2bc not 2bc, this is the mistake that cost me a mark in trial 1 for 2u.

 

[theind1996]

lol I'm the other way around.

Really? haha

 

[bleakarcher]

Really? haha

I hate having to memorise shit.

triangle ADC?

but yeah, i think i get it.

 

[theind1996]

in triangle adc

oh shit

 

[Shadowdude]

how is ADC a triangle

it's a straight line

 

[wildchild666]

cheers brah

how is ADC a triangle

it's a straight line

typo or something obviously.

Wait so how did I lose a mark for this?

Got 49/60 for this test...
