## Lesson Note on Mathematics SS2 First term

**Week 1 – Logarithm of Number Less Than One**

**Overview – **A logarithm is a mathematical operation that expresses the power to which a base must be raised to. This week, we shall learn about logarithm of number less than one. To learn more, Click

**Week 2 – Approximation and Percentage Error**

**Overview – **Sometimes we may only need to calculate things to a certain degree of accuracy. This brings us to approximations and estimations. Approximation refers to a process of getting a result that is close to but not the exact result. Estimation refers to giving an educated guess of a number. This week, we shall learn about approximation and percentage error. To learn more, Click

**Week 3 – Arithmetic Mean: Geometric Progression**

**Overview – **Geometric progression is a sequence of numbers in which each element is obtained by multiplying the previous number by a constant referred to as the common ratio. Arithmetic progression refers to a sequence of numbers which have a common difference between any two consecutive numbers in the sequence. The arithmetic progression and the geometric progression have different formulae. This week, we shall learn about the arithmetic mean: geometric progression. We shall also learn about the arithmetic progression. To learn more, Click

**Week 4 – Finding Common Ratio: Geometric Mean, Sum of Term of GP, Sum of Infinity**

**Overview – **Common ratio is the number multiplied must be the same for each term in the sequence. It is the ratio between two consecutive numbers in the sequence. The geometric mean is a special type of average where we multiply the numbers together and then take a square root, cube root. This week we shall learn about finding common ratio: geometric mean, sum of term of GP, sum of infinity. To learn more, Click

**Week 5 – Revision of Factorization of Perfect Square: Solution of Quadratic Equation by the Method of Completing the Square**

**Overview –** In factorization of perfect square we will learn how to factor different types of algebraic expressions using the following identities. This week, we shall learn about the factorization of perfect squares. We shall also learn how to solve quadratic equations by using completing the square method. To learn more, Click

**Week 6 – Construction of Quadratic Equation from Sum and Product Roots, Word Problems Leading to Quadratic Equation **

**Overview – **This week, we shall learn how to construct quadratic equation from sum and product roots. Using the formula “ax

^{2}+ bx + c = 0”, there are steps that are taken to get the final answer to a particular quadratic equation. We shall also learn about how to solve word problems leading to quadratic equation. To learn more, Click

# Week 7 – Graphical Solution of Linear and Quadratic Equation

**Overview –** The basic idea behind solving by using graphs is that since the “solutions” to “

*ax*

^{2}+

*bx*+

*c*= 0″ are the

*x*-intercepts of “

*y*=

*ax*

^{2}+

*bx*+

*c*“, you can look at the

*x*-intercepts of the graph to find the solutions to the equation. This week, we shall learn about the graphical solution of linear and quadratic equations. To learn more, Click
