SPM Form 5 Add Maths_Chapter 09 Basic Motion along the straight line

Direction is very Important in Vector quantities:
(a) Displacement= change in position which includes both magnitude and direction
(b) Velocity = displacement/time
      V=dx/dt
(c) Acceleration= change in velocity = velocity/time;
     a= dv/dt = d/dt(dx/dt)

Direction is Not Important in Scalar quantities:
(a) Distance
(b) Speed= total distance/time which only describe how 'fast' is a particle moving without telling which direction

SPM Form 5 Add Maths_Chapter 08 Probability Distributions

It is important for students to learn on how to read and use the standard normal distribution diagram in order to master this chapter. The video below shows a basic skill that students should have in solving these kind of questions.

Here is the second part of it which students will know how to solve the SPM type of questions.

SPM Form 5 Add Maths_Chapter 07 Probability

Probability tells how likely of an event will happen or how likely a statement is true.
Suppose there are two events, A and B are independent to each other, the Probability will be calculated as: P(A and B) = P(A)P(B)

If the two events are dependent to each other, there are two cases as shown below:
Mutually Exclusive: P(A or B) =P(A)+ P(B)
Not Mutually Exclusive: P(A or B) = P(A) +P(B) - P(A and B)

The video below teaches students to use the tree diagram in solving the probability question besides categorizing the tree diagram for 1st time, 2nd time and the situation of "without replacement"

To enhance students understanding, the video below uses one of the famous type of probability question in Add Maths using tree diagram to solve.

SPM Form 5 Add Maths_Chapter 06 Permutations and Combinations

In this chapter, students should know the difference between the Permutation and Combination in order to understand when to apply nPr or nCr.

Permutation is when the order is important in the arrangement.
Combination is when the order is not important in the arrangement.

The video below uses one of the famous question in SPM as an example.

SPM Form 5 Add Maths_Chapter 05 Trigonometric Function

In this chapter, it is important for the students to learn about the shape and sketch the sin, cos and tan graph.

Sine Graph always started with a "∩" follow by a "∪"
Cos Graph always started with a "∪" follow by a "∩"

Tan Graph is a bit different with the other two graphs, however, once the concept is understood, students will find it easy.

Trigonometric does not only contain Sin Cos Tan but also the inverse of these three function, thus introducing Cot Sec and Cosec in the below video. Students will learn the basic formula in solving Paper 2 with the use of Past Year Questions as example.

The video below explains about the relationship between "pi" and "degree" besides teaching students on getting two answers from the value.

SPM Form 5 Add Maths_Chapter 04 Vectors

Students should take note that Scalar is a quantity which only has the magnitude whereas, Vector is a mathematical object which comprises magnitude and direction.

Something EXTRA here!!!! Interesting knowledge about the relationship between hexagon and octagon with vectors.
