what i meant by my question is what are the main proofs that we need to have a great understanding of ie which questions of which genre appear most in test scenarios. Just as an example would a question on exponentials require you to know WHY differentiating (e^x) an exponential gives you the...
What are the main proofs we need to know in 3u? Things like the trapezoidal rule, simpsons rule and log proofs dont make sense to me...do i still need to learn them and understand them?
Why do you need to monitor phosphate? All i have so far is because it can cause algal blooms which kills marine life. Is there anything else i need to add?
what is the quantitative test for phosphate? No clue
What is the quantitative test for lead? I think its AAS not sure though
So my understanding is that trading blocs are formal agreements that exclude other countries; do free trade agreements also exclude countries, or is it an agreement between set countries that is open to other countries?

Realise the fraction
and that gives you
(cos a)(cos b)-(cos a)(isin b)+(cos b)(isin a)+(sin a)(sin b) note: denominator = 1 as sin^2b+cos^2b=1
=cos(a-b)+isin(a-b) using trigonometric identities (cos expansion and sin expansion)
Re: HSC 2016 3U Marathon
equation of pq = y=((p+q)/2)x - apq
For this to be a focal chord must pass through o,a
sub o,a --> a=-apq therefore pq=-1 (not too sure if this would count as proof that its a focal chord but if i recall the textbook states this is general form)
b)d(1/4a.x^2)/dx...
Dotpoint 2.6 says analyse progress in the recent development and use of a named biopolymer
What are the recent developments of biopol i was thinking about how they take the strain from cupriavidus metallidurans and put it into E.Coli but they started doing that like 10 years ago, is this still...
