## Lesson Note on Mathematics SS3 First term

Week 1 – Theory of Logarithm

Overview – This week, we shall learn about the theory of logarithm. We shall be introduced to the laws of logarithms – quotient law, product law, power law, root law, fractional power and change of base. We shall also learn how to apply the laws of logarithm in solving problems involving calculations. To learn more, Click here…

Week 2 – Surds: Meaning of Rational and Irrational Numbers Leading to the Definition of Surds

Overview – There are rational and there are irrational numbers. Surds are irrational numbers that cannot be simplified into whole numbers. Rational numbers are numbers that can be expressed as part of a whole number. This week, we shall learn about surds and how to solve problems on surds. To learn more, Click here……

Week 3 – Application of Surds to Trigonometrical Ratios

Overview – Having been introduced to surds, this week, we shall learn how to apply surds to trigonometrical ratios. To learn more, Click here

Week 4 – Matrices and Determinants

Overview – A matrix is an array of numbers. The determinant of a matrix is a special number that can be calculated from a square matrix. Matrices can be added, subtracted and multiplied by a constant and even by another matrix. This week, we shall learn about matrices and determinants. We shall learn how to calculate problems on matrices and how to calculate determinants. To learn more, Click here…

Week 5 – Linear and Quadratic Equation

Overview – A linear equation looks like any other equation. It is made up of two expressions set equal to each other. The graphs of linear equations are always lines. Quadratic equation refers to polynomial equation that have a general form of ax2 + bx + c = 0, where a, b and c are co-efficient. This week, we shall learn about linear and quadratic equations. To learn more, Click here

Week 6 – Word Problems Leading to One Linear – One Quadratic Equation Surface Areas and Volume of Sphere and Hemispherical Shape
