Matrices

Follow hints using a little coordinate geometry, plane geometry and trig to see how matrices are used to work on transformations of the plane.

Explore the transformations and comment on what you find.

Matrices and Complex Numbers combine to enable us to create four dimensional numbers.

Use matrices to find out how much cake I eat.

Use matrices to model this popular party game.

Follow hints to investigate the matrix which gives a reflection of the plane in the line y=tanx. Show that the combination of two reflections in intersecting lines is a rotation.

Given probabilities of taking paths in a graph from each node, use matrix multiplication to find the probability of going from one vertex to another in 2 stages, or 3, or 4 or even 100.
