How well are you with numbers? Do you understand all different types of numbers and know how to work with them? Check the following links which will develop your understanding of these numbers necessary to pass your maths exams.
How to use Matrices with Transformations
You have learned several types of transformations. I have explained Reflections, Rotations, Translations and Enlargements to you and you even know that sometimes you are asked to carry out a combination of these types of transformations. But a transformation can also be represented by a Matrix. In this part I will explain to you how to carry out a Transformation when given a Matrix an also how to construct a Matrix when given an object and its image. So study the videos carefully during your maths revision and pass your IGCSE GCSE Maths exam!
