About Mr. Momanyi
Mr. Momanyi is a Mathematics teacher at Anestar Boys High School. Anestar Boys is one of the best schools in Kenya having scored a mean score of 9.7 in 2019 KCSE exam. The school was position 11 in Kenya hence one of the reasons for trusting Mr. Momanyi with the content he has prepared.
Introduction
In form 2 you studied various forms of changes/transformation, i.e., reflection, rotation, enlargement and translation. In the lessons, objects points were plotted on a Cartesian plane and in case of any change/transformation, the image obtained was compared with the object.
In form 3 you studied matrices of different orders e.g. 2*1, 2*2 among others. Besides multiplication procedures of these orders were covered as well.
In this video tutorial matrices are combined with transformation. So you are going to learn how objects are transformed or changed by given matrices hence the topic, Matrices and Transformations.
It is important therefore to understand what you studied in form 2 and form 3.
Matrices of Transformation
Example 1:
The above example is solved in the video tutorial
There is an assignment at the end of the tutorial. You are supposed to attempt the assignment. Tutorial 2 opens by solving the problem or assignment given in tutorial one.
The second part of the video tutorial covers:
Finding the matrix of Transformation
In this case, we are given both the object and the image points and hence required to look for the matrix of change. We shall apply the matrices multiplication procedure and the concept of simultaneous equations.
Note that the tutorials are covered in the format provided by the ministry in terms of topics and the content.
The explanations in the video tutorial are simple and straight to the point. Also, a well-written guide is used to avoid giving misleading information. See you in the next tutorial on Mathematics Matrices and Transformation (continuation)
