34. EOY Revision Starts - Trigo Identities [2021]

Overview

1. 34. EOY Revision Starts - Trigo Identities [2021]

This week, we covered on Trigonometry Identities. We learnt some formulae to connect the relationship for trigo2. It is important to be familiar with these formulae as it helps us simplify more complicated trigonometric equations and to solve some proving questions. As we are exploring more question types, we noticed that these questions can involve algebraic factorisation and special identities! It gets tougher when we need to consider a list of possible trigo-identity conversions. Play around with the trigo formulae more frequently and you will be fine.
