WORKED SOLUTIONS AND PAST PAPERS

JANUARY 2006 (click to download the paper)

These solutions have been contributed by Year 12 Hawthorn High School 2012. Simply the best!!

Question  Topic  Solution contribution by: 
1
Coordinate Geometry

Emily- Emily made a common mistake. She USED the information that required a proof. It cost her 2 marks.

Robert- Robert provided two alternative approaches to the proof that k=5 in part b. You should try to understand

his approach in his alternative solution. Remember that the equation of a line requires only ONE coordinate if the

gradient is known. Robert used BOTH coordinates to obtain TWO different equations for the SAME line.

Hence he equated and found k.

Surds

Tamar has a correct solution but the workings are difficult to follow. This has not caused a problem in this case but it increases

the potential for error.

Danielle also has a correct solution. Her presentation of work is clear and logical and a potential error was prevented when she

reviewed her solution to spot a further simplification of a surd.

Equation of Normal

Bethan has produced a solution that could be published. 

A common error was to find the EQUATION OF THE TANGENT and not the Equation of the NORMAL so

TAKE CARE WHEN YOU READ THE QUESTION!

Transformation of Graphs

The original graph went through the ORIGIN but the coordinate (0, 0) was not given specifically.

Corey lost a mark because he did not identify the new coordinate that the ORIGIN was transfered to.

Rachel gained full marks as she identified the ORIGIN as being a key coordinate that is changed under the transformation.

Roots of Quadratics

Hannah has made a common error with signs. The discriminant involves a subtraction and so we must take care with negatives and brackets.

She still tried to "fiddle" the solution and went on to score 5 out of 7 marks. Never give up when the question moves on to use something that is given.

Factor and Remainder Theorem
Amy has full marks in this question but can target improved communication and logical presentation of her working. She has mathematical inconsistencies and incorrect terminology.
Binomial Expansion

Danielle has a solution to both parts of this Binomial question, in which she demonstrates clear communication of the difference between a TERM and a COEFFICIENT.

She uses Pascals Triangle where appropriate and the Binomial formula where Pascal's Triangle can not be used.

8 Differentiation

Ryan gives a nice "first Principles" of Differentiation proof. Many students miss minor details and lose marks. The proof must be flawless.

A tricky differentiation using rules of indicies caused a problem for many students but not Emily

9 Completing the Square
Negative x squared terms always cause a problem for students as sign errors are easy to make. Nuella had no problem with this question.
10 Stationary Points

Good spot! Bardmeister has the correct answer in his Winter 2009 solutions.
