What how did that happen? Your external mark gap must be far greater than your internal mark gap?

But the argument is 2.

The answer is wrong.

I vote for ninety percent + for some other kids who only post on the 4u math board.

Yea studyfreak thxs for that. Its what i thought as well. But can there be 2 answers? Cause the book's solution is pretty sound as well.

I think your right.

P(x) = x^4 + cx^2 + e, where c and e are real If sqrt3 + i is a root, determine c and e, then factor into quadratic factors with linear factors Here's my attempt: Since c and e are real, then sqrt3 - i is a root (complex conjugates theorem) Also P(-x) = P(x) therefore P(x) is even...

When I intergrated: 1/sqrt(x)sqrt(1-x) = I, Ive got sinh sqrtx. This i used a subsitution x=u^2 However, expanding the bottom; I = 1/sqrt(x-x^2), then chaging the denominator to a perfect square: I = 1/sqrt (1/4 - (1/2-x)^2), then using the same sin inverse identity, i got a complete different...

Well if Peter Garret had some experience as a tradie, maybe he wouldnt of sucked as much. Just saying.

Sarcasm just for the sake of sarcasm.

Bit biased isn't it? Any religious nut could call him a stupid imbecile. The only real way to measure a poli's intelligence would be making them sit the same the same test on the same topics /issues that concern parliment. The closesest thing i can think of is a uni degree

Yes all the ministers sit at home at night writing up bills word for word, and thinking about ideas that will fix up the country.

Do we have to know all the speeches or just select a few?

How do you do middle of sequence questions? They kill me and takes a very long time to do. Help?

In this question Deduce cos4a = 8(cosa)^4 - 8(cosa)^2 + 1 hence solve 8x^4 - 8x^2 +1 = 0 Ive done all except this part: Deduce exact values of cos(pi/8) and cos (5pi/8) Im using sum and product of roots and im getting cos^2(5pi/8)cos^2(pi/8) = 1 and cos^2(5pi/8) + cos^2(pi/8) = 1 But i...

To all the employees/managers out there of retail stores have you had any experience with corporate sponsorship of schools? I am not talking about anything big, but just some small support for the school, like sporting equipment per say. Who would I contact in such a situation? If I am...

Whats with all the hostility? Chill man chill

Could someone perhaps enlighten me on the difference between these two concepts? For it is thoroughly confusing.

Lolz, mine are wk 5 n 6 nxt term.
