BUT!!! what if the question asks for 2 only, not 3, 4 or 5 of the same suit, then there would be a probability less than one, but the question doesn't specify, so im just being difficult

P(x) is an odd polynomial of degree 3. It has (x+4) as a factor and, when it is divided by (x−3) , the remainder is 21. Find P(x).

CBF, mathematical induction is easy anyways

ii)horizontal asymptote: y=xsin(1/x)??

best thing about being an accelerant though, is that you get a shot at pwning the 2u students

i hope they aren't too strict on circle geo reasoning, how close do you have to be to the actual reasoning as far as wording goes?

good luck all in 4u on monday, while i enjoy my 2u test :P

correct

I liked that question

heres a nice one from the 1998 HSC paper, integrate, using z=x-1/2 \int \frac{1}{\sqrt{x(1-x))}}dx

post a question muzeikchun :)

u have to remember to evaluate C because u have integrated

expand then integrate \binom{n-1}{0}x+\binom{n-1}{1}x^{2}/2+\binom{n-1}{2}x^{3}/3+...+\binom{n-1}{n-1}x^{n}/n let x=0 to evaluate C, C=-1 let x=7 LHS= as u have shown RHS = ((8)^n)/n -1 =((2^3)^n)/n -1 as required yeh i gave up on the syntax

ah ok, might take me a little while, im new to this cool fx syntax

well if u consider (1+x)^n(1+1/x)^n, that gives you square coefficients for x^n, but i dont know where the (n+1) comes from, because that would hint that there is a differential, but then it should be n not (n+1) gahh

you got me! what's the answer?

could you repost that question with the c's denoted correctly? because it looks like a good question and it will bug me if i dont solve it :)

are you sure you have denoted your C's right?

i) 0.0442 (4dp) ii) 0.0179 (4dp) conformation of correct answer please :) OK new question.... \int (1+tan(y))^{2}

brilliant :) good luck in 4u on monday and 3u on wednesday
