WELCOME TO NADY'S MATHS HOUSE!

QUIZ:

TRANSFORMATION III 

Transformation P is a reflection in the line x = -1 and transformation R is a rotation of 90 degree clockwise about point (1,2)

(i) State the coordinates of the image of point M(-2,5) under the combined transformation RP.

(ii) If the point S (-2,1) is the image of point T (x,y) under the transformation PR, state the value of x and y. 

~Good Luck~

Exercise: Matrices

(a)  If    , find the value of k and of n.




(b) Write the following simultaneous linear equation as a matrix equation. 

Hence, calculate the value of x and y using matrices.

QUIZ:

Bearing


Diagram 10 shows three points, P, T, and S, on the horizontal plane.

Given that the bearing of T from S is 280 degree.  Find the bearing of P from T.

~Good Luck~

QUIZ:

In the diagram 5, O is origin, point P lies on the y-axis and point Q lies on the x-axis.
(a) Determine the gradient of straight line PQ.
(b) Find the equation of straight line RS and hence, find the value h.

QUIZ:

 Gradient and Area Under A Graph

Diagram 4 shows the speed-time graph of a particle for a period of 20 seconds. Given the total distance travelled by the particles for the period of 20 seconds is 170m. 

(a) State the uniform speed, in m/s, of the particles.

(b) Calculate the value of k.

(c) Find the average speed, in m/s, of the particles for the period of 20 s. 

Exercise: Transformation III

Study Time!!!....^^)...

Let Y1 = rotation of 90 degree anticlockwise about point (-1,0) and Y2 = rotation of 180 degree about point (0, 1).

After complete this exercise, please submit to  me

Exercise: Graph of Function II

Note:


  This exercise for graph  function....(^v^)...

Extra Exercise: Number Bases

There are few exercise for all the student..(^o^)

Chapter 8: Bearing ...~Form 5

1. Compass Direction

2. Bearing

    

    The bearing of a point/place from a reference point/position is the angle measured at the reference point from the true north in a clockwise direction. It is always written as a three-figure number.

For example,

The bearing of A from O is 020 degree.

The bearing of B from O is 155 degree.

The bearing of C from O is 230 degree.

The bearing of D from O is 320 degree. 

Chapter 6: Gradient and Area Under a Graph..~FoRm 5

(a) Distance - time graph of an object:

    * The gradient of a distance - time graph gives the speed of particles.

                   

(b) Speed - time graph of an object:

     * The gradient of a speed-time graph gives the rate of change of speed of a particle.

     * The area under the graph represents the distance travelled.

     * Positive gradient represents acceleration.

     * Negative gradient represents retardation or deceleration.

     

ATTENTION TO 4A & 4B STUDENTS

DIAGNOSTIC TEST

To all new students of 4A & 4B,

We will be running a Diagnostic Test during Maths period tomorrow. 

This Diagnostic Test is basically to test your basic maths knowledge. 

There are 20 subjective questions overall.

Please be at Library in order to sit for this test during Maths hour which is 11.10 a.m until 12.30 p.m.

No Mathematics notes are allowed!

ATTENTION TO 5A, 5B & 5G STUDENTS

QUIZ : TOPIC NUMBER BASES

I would do a short quiz regarding the topic NUMBER BASES for 5A, 5B, and 5G during our upcoming Maths class. 

The quiz will be 10 objective questions and also 4 subjective questions.

The marks for this quiz will be taken for 10% continuous assessments.

 

DO YOUR BEST!  GOOD LUCK!

ATTENTION TO 5B STUDENTS

EXTRA CLASS ON TOMORROW NIGHT

To all 5B students, I have arrange an extra class for you which will be held on tomorrow night (Wednesday 15/2/12) at Multimedia Room (9 p.m.)

We will discuss the exercises for topics Gradient & Area Under A Graph and Angle of Elevation & Depression. 

Thus, don't forget to bring along the handouts of exercises for these two topics that i gave you earlier.

Also, make sure that you've complete all the exercises before you come to class!

See you soon!!

Notes : Transformation III (Form 5 - Chapter 3)

EASY NOTES TO UNDERSTAND THIS TOPIC

1. Translation is a transformation in which all points are moved to a new position through h units parallel to the x - axis and k unit parallel to the y-axis. It is written as translation 
.

(2) Reflection is a transformation in which all the points on a plane are flipped over onto the same plane in the axis of reflection. For example, reflect the object in the y-axis (the line, x =0).

                                                  

(3) Rotation is a transformation in which all the points rotate in the same direction through the same angle about a point. For example, rotate the triangle PQR about O  through 90 degree clockwise.

(4) Enlargement is a transformation in which all the points of an object extend from the centre of enlargement at a constant ratio. For example, enlargement of square ABCD at O with scale factor 2. 

                                                     



Combination of Transformation 


If A and B are two transformations,
AB = Transformation B, followed by transformation A.
BA = Transformation A, followed by transformation B.
A^2 = Transformation A executed twice.

THE GRAPHS OF FUNCTIONS

THE REGION REPRESENTING AN EQUALITY IN TWO VARIABLES

Notes : Matrices ( Form 5 - Chapter 4)

LETS LEARN ABOUT MATRICES !  (^_^)

First of all, we should know what is column and row....

(1)  is row matrix ( contains only 1 row)....

(2) 
      is a column matrix (with only 1 column).... 
  

Remember This Formula:

(a) Addition of Matrices:

    

(b) Subtraction of Matrices:

(c) Multiplication of Matrices:



(d) Inverse Matrix


     Inverse matrix of 

 

     where ad - bc not equal with zero..


   * if the determinant ad - bc equal with zero, then the matrix has no inverse.


   * Example:

                                         
         
       Then inverse of M,   
                                                           

(e) A matrix multiply by its inverse 
     = identity matrix
