In this 'mesh' of sine graphs, one of the graphs is the graph of
the sine function. Find the equations of the other graphs to
reproduce the pattern.
An account of how mathematics is used in computer games including
geometry, vectors, transformations, 3D graphics, graph theory and
Follow hints using a little coordinate geometry, plane geometry and

This problem is about combinations of reflections. The problem
Reflect Again uses matrices to show
that the combination of two reflections in intersecting mirror
lines gives a rotation.
