Table of contents


In this course, we will cover all the trigonometric chapters tested in O Level Additional Math (also called A Math or Add Math in short). This course is based on syllabus 4049. This is a content-rich chapter, as there are many concepts that you need to learn. I start off by going through concepts, and then we will try many questions together. The purpose of this course to allow you to be able to do your Add Math questions by yourself after you complete this entire course.
The topics that we will cover include:
– A revision on trigonometry (What you have learnt in elementary mathematics)
– Degrees and Radians
– Curve sketching
– Principal values
– Four Quadrants
– Solving Trigonometric equations
– Trigonometric identities
– Double Angle Formulae
– R Formulae

This is a FULL course on trigonometry (based on the Singapore O Level Add Maths syllabus – syllabus 4049). Not only will I be going through concepts, but I will also walk you through the questions step-by-step. We will also go through step-by-step past prelim questions from various schools. Ultimately, the goal of this is to help you understand the concepts tested in trigonometry and be able to do the questions and score!

This is a complete course on the entire trigonometry tested in O Level Add Maths. It’s also the course that I conduct for my students taking the O Level A-Math. The entire course is usually covered in multiple 2-hour lessons. But, now, you have the opportunity to watch the entire class on-demand, anytime you like and re-watch it as many times as you want.
