This task considers using metal rods to make a triangular framework. The metal rods have lengths that are whole numbers. Students must work out how many triangular frameworks can be made with the longest side being 7 metres. The solution involves being methodical in listing examples, and using inequalities to...

This short task contains two questions on applying trigonometry.

The topics covered are:

• Linking sine, cosine and tangent
• Using Pythagoras to determine a length in a triangle and then give the tangent of an angle in surd form
• Using the Pythagorean identity sin2(x) + cos2(x) = 1...

This resource contains twelve problems requiring students to explore the properties of the functions of sine, cosine and tangent. Students explain which is the odd one out, state which functions can be represented by which graph, devise questions which give a certain set of solutions and state whether statements...
