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...

Mathcentre provide these resources which cover aspects of trigonometry and are suitable for students studying mathematics at A Level, as well as those students for whom mathematics is an integral part of their course. Some of the topics covered include the trigonometric ratios, using Pythagoras’ theorem, cosecant,...

Mathcentre provide these resources which cover aspects of trigonometry, often used in the field of engineering. They include the trigonometric ratios, using Pythagoras’ theorem and working with the sine and cosine rules.

Comprehensive notes, with clear descriptions, for each resource are provided, together...

This RISP activity gives students four properties - one side is 3cm, one angle is 90 degrees, one side is 4cm and one angle is thirty degrees. Students are required to find as many triangles as they can which contain any three of these four properties. Once the triangles have been found, students are asked to find...

This sub-collection of resources from the Virtual Text Book collection contains five resources designed for use on an interactive whiteboard to aid the teaching and learning of a variety of topics in ‘Trigonometry'. Each resource is an interactive Excel worksheet to encourage teacher-student interaction. The topics...

The first of two RISP activities, Radians and Degrees, students are set the task of finding an angle whose sine value is the same whether measured in radians or degrees....

This collection of interactive excel sheets looks at a circle of radius 1 and the corresponding values generated for cosθ and sinθ.

The first interactive sheet illustrates that for the unit circle, X = cosθ and Y =...

Carom Maths provides this resource for teachers and students of A Level mathematics.

This presentation shows how, when placing triominoes onto a chessboard, there is always one empty square. An algebraic proof is developed to show that the empty square will always appear in the same location, or in one of...

Published in August 2014, this is the final report of the three-year evaluation of the Triple Science Support Programme (TSSP) and the two year evaluation of Triple Science Networks (TSN).

The full collection of STEM Learning impact and evaluation research reports can be viewed...

This Catalyst article looks at peatlands which usually conjures up images of bleak, boggy hillsides across Northern Europe, Russia and the USA. But peatlands are also found in the tropics. These currently act as a significant store of carbon, yet these valuable ecosystems are under threat; their disappearance could...

This poster illustrates how expertise from designers, engineers and technologists is used to design and manufacture an innovative snowboard. It helps to illustrate how STEM industries offer many exciting career opportunities.

In this Catalyst article an experiment is described in which the formation of clouds can be replicated. The experiment requires nothing more than a plastic bottle, warm water, matches and a small thermometer.

This Catalyst article explains how some gases can be poured, demonstrated by an experiment using carbon dioxide gas.

This article is from Catalyst: Secondary Science Review 2011, Volume 22, Issue 2.

Catalyst is a science magazine for...

This Catalyst article investigates how honeycomb (cinder toffee) is made using a thermal decomposition reaction to produce the gas bubbles. Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down...
