Nature of fixed points of a 2D dynamical system.

These examples are either centres or spirals.

Using differentiation to find the tangent and normal to a line at a given point

This question tests the student's knowledge of the remainder theorem and the ways in which it can be applied.

Simple inequalities - finding values of x

This is a set of practice questions for the non-right-angle trig component of the Australian year 12 Mathematics Standard 2 course.

It asks questions about

• finding sides and angles of right angle triangles,
• finding areas of triangles,
• using the sine rule,
• using the cos rule,
• bearings, and
• radial surveys.

A graph is drawn. A student is to identify the derivative of this graph from four other graphs.

Find the inverse of a composite function by finding the inverses of two functions and then the composite of these; and by finding the composite of two functions then finding the inverse. The question then concludes by asking students to compare their two answers and verify they're equivalent.

Students are shown a graph that simultaneously plots cost and revenue lines. They are asked to identify the break-even point.

They are asked to give the x- and y- coordinate values.

The graph is randomised, but it is set up so that the point of intersection lies on gridlines.
