01What this module asks of you

The 5 syllabus dot points in Vectors

These are the statements the Mathematics Extension 2 syllabus makes about Vectors. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.

  1. 01

    Three-Dimensional Vectors

    Vector algebra in three dimensions, the dot product, and the geometric meaning of magnitude and direction in space.

  2. 02

    Vector Equations of Lines

    Representing a line by a point and a direction, and identifying parallelism, intersection and skew lines.

  3. 03

    Vector Equations of Planes

    Planes described by a point and a normal, the relationship between a line and a plane, and distances to a plane.

  4. 04

    Vector Proofs

    Using vector methods to prove geometric results in two and three dimensions without coordinates.

  5. 05

    Vectors and Curves

    Motion along a curve using vectors, including velocity and acceleration components and the geometry of the path.

02How it is examined

What a Vectors question asks you to do

HSC Mathematics Extension 2 - Trial Paper Shape is 100 marks in 180 minutes. Questions on Vectors are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Mathematics Extension 2 uses.

Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.

03Where this module sits

Vectors in the Mathematics Extension 2 course

Vectors is module 2 of 6 in Mathematics Extension 2. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.

Find the Vectors dot points you have never been asked

Dux diagnoses Mathematics Extension 2 dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
