The picture shows some curves in the family of y = x cubed. Can you find the graph of this function and the equations of the other graphs? In this workshop guide you will find more examples of this type of ‘inverse problem’ where the learner is given information and has to […]
Some practical activities to help learners to tell the time on a 12 hour or 24 hour clock and to work out the lengths of time intervals.
This guide offers many suggestions for practical surveying tasks that can be done without needing any expensive equipment. Applications of trigonometry include measuring the length of your shadow and relating this to the angle of elevation of the sun and the time of day, measuring heights of buildings, trees and towers, navigation, […]
This workshop guide provides learning activities that explore the ways in which arithmetic and geometric series are used in simple and compound interest calculations related to loans (including pay-day loans) , investments, annuities, hire-purchase, inflation etc. and there is an explanation of how APR is calculated. Ideas are given for practical ways […]
This workshop reviews reduction formulae in terms of rotations and reflections. It offers learning activities that involve sorting and solving trigonometric equations and finding general solutions, or solutions within a
given domain, using known identities and graphical or unit circle representations. Suggestions are given organising group activies and learners presenting and explaining their ideas […]
This workshop guide reviews the number systems that learners have met and expands number concepts to include complex numbers. Learning activities involve matching graphs to linear and quadratic equations and their solutions within different number systems.
There is discussion of the historial evolution of mankind’s concepts of number and parallels are drawn […]
The sum of the first 48 terms of an arithmetic series is 4 times the sum of the first 36 terms.
What is the sum of the first 30 terms?
The area of triangle PQR is 3√3 square centimetres. Angle PRQ is 60 degrees and RQ is 4 centimetres longer than PR.
