Triangles in a Spiral

This activity is based upon a practical task to fit a set of similar triangles into a spiral. It is in two parts, the first of which is more accessible.

In Part 1 students are presented with a series of different sized similar triangles. These fit together to form a spiral and students look at how many are...

Triangular frameworks

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...

Trigonometric functions

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...

Trigonometric Ratios

Royal Navy Search and Rescue helicopters provide cover to large sections of the UK coastline, offering support to coastguard services 365 days a year.

These materials from Defence Dynamics encourage the use of problem solving skills and knowledge of trigonometry to directly assist the Royal Navy in a series...

Trigonometric Ratios of Any Angle

The objectives of this PowerPoint are for students to: • understand what is meant by: circular functions; quadrants; positive angles; negative angles.

• recall the main characteristics of the graphs of y = sin x, y = cos x and y = tan x.
• consider the main trigonometric ratios in all 4 quadrants....

Trigonometrical Functions

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...
