yeah that's what I meant...

do it.. you can always drop if you find it difficult

it goes through a process of aligning I think.. where judges look at the question and say and Band E4 student should be able to: then they adjust the marks. Anyway, I suppose everyone here is interested in UAIs.. so forget what BOS does. UAC works on raw marks

he wants answers.. try drbuchanan's site

I will expand on the by parts bit: basically... you don't want to get something more complicated than you started with. and the following indicates complexity high powers are more complicated than low powers irrational terms (squareroots cube roots etc) are more complicated than terms...

84/120 that's band E4 I think... but BOS bands doesn't work on raw marks.. they change what questions are worth for the band thing.

by parts generally(there are exceptions): you want to differentiate polynomial parts, inverse trig parts and logarithm parts. integrate trig and exponentials. hmm basically it.. 2)the book's right... you're wrong. revise your trigonometry identities

Books tend to get the blame when something happens.. they don't speak

divide :P alternative.. you can use that factoring program I used if you are lazy, check my other post

question 2 player 0 wins strategy: basically you want 3 0s in a row/column or 4 0s each occupying a corner of a rectangle: by '4 at corners of rectangle' it could be: 0 1 0------0 0 1------1 0 0------0 1 0 0 1 0------0 0 1------1 1 1------1 1 1 1 1 1------1 1 1------1 0 0------0 1...

question 1: pick 2 points draw the big circle through it. you have 3 points remaining to place in the 2 hemispheres, so.. one of the hemispheres must have 2.. these 2 points + teh 2 on the big circle will give 4. done

it's 4 UNIT MATHEMATICS denise arnold graham arnold or CAMBRIDGE MATHEMATICS 4 UNIT they are the same

a_1^2 is confusing and the subscript takes too long to type

i= arbitary integer, used traditionally for the dummy variable in sigma notation, also, usual variable for the 'for' loop in programming languages. a(i) is just like a_i

it's a median mark of 1.. mean would be higher

incidentally that also specifies the equality condition: a(i)/b(i) = constant.

I know about that.. and my friend said his calculator is on the list

1) there are 1024 factors.. (10 prime factors, each to the power of 1, so it's 2*2*2*2*2*2*2*2*2*2)

by the way {x:x=2^n + 2} are also solutions

enak, where did you see the question?
