You can do this: Pretend it's a quadratic but just replace x2 with x4 and x with x2 i.e. x^4 - 29x^2 + 100 = 0 What two numbers multiply to give 100 and add to give -29? -25 and -4 (x2-25)(x2-4) = 0 Now let each factor be equal to zero for values of x. x2-25 = 0 x2 = 25 x =...

Ask the Board of Studies.

Wow. You got 97 and 98% in music 2 and extension respectively in year 8 (assuming you're 16 years old this year)? I'm very impressed. You can use the HSC forums this year since you have done the HSC maths and extension 1 exams in 2008, just not preliminary yet.

Too simple and cliche imo.

1. White settlement destroyed Aboriginal links with the Dreaming - the key beliefs regarding creation and existence. The main aspects of the Dreaming are kinships (groups, clans), obligations to the land and people, and ceremonial life (e.g. balance rites, initiation etc). Dispossession from the...

From past experience you are going to well (provided you didn't bomb out in the exam). I got 76% in english trial but 94% in SC exam; 78% in geography trial, 98% in real SC exam. So in summary, don't worry yourself. You did the best you can do, what's done is done. Good luck. I'm sure you...

Re: How Does The Sc Marking Process Work? Incorrect. If that was the case then nobody would get odd numbered marks. Aligning is basically where everybody's raw marks are increased (usually) to the cut off marks decided for each band. E.g. a band 6 might be 85 raw as the cut off i.e. 90%. If...

Re: Area of Study practice essay questions Here's a creative response question: "He is the eternal alien, the outsider." --- Use this as the key idea for a narrative on the concept of belonging.

Year 10 PDHPE isn't really a subject. Well for our school anyway.

Behind but coping. Only just. Chemistry assignment due in week 7. :apig:

Wow.

Well deserved. :wave:

Re: Area of Study practice essay questions Belonging relies on both conformity and individuality. What is your view? Compose a persuasive response with reference to the prescribed text and 2 other related texts of your own choosing. You will be assessed on: - Understanding of the concept...

Past HSC papers are definitely the way to go. Find them on the board of studies website. Maxima and minima problems are usually in the latter part of the paper i.e. questions 8-10.

2cos2x -cosx = 2-secx 2cos2x -cosx = 2-(1/cosx) ---- write sec in terms of cos i.e. secx = 1/cosx 2cos3x -cos2x -2cosx +1 = 0 ---- mutliply through by cosx to destroy the fraction and move all terms to the left hand side of the equation cos2x(2cosx-1) -1(2cosx-1) = 0 ---- group in pairs to...

The same idea goes for the HSC exams.

Assignments are good because there's less pressure/time factor. Assessments are good because there's no set work and you can get away with a fair degree of procrastination. But in the end, it's 50/50. It doesn't really bother me which type I have, just as long as I can perform my best in...

A mark somewhere in the 80%+ range can just about assure you a band 6 (90+) due to the moderation process (but this cut off does change from exam to exam).

99.99999/100 times it's aligned up. This is to allow more of the state to gain a band 2+ (50%+).

Goodnight. Get your rest.
