1. 33. EOY Revision Starts - Trigonometry Eqn [2021]
This week, we covered on Trigonometry Equations. From the concept of ASTC and Trigo Graphs, we learnt to solve trigonometric equations. To solve for ALL possible angles, we learnt to manipulate the given domain to what we want. As we are exploring more question types, we noticed that these equations can involve algebraic factorisation! It gets tougher when we need the negative angles from the annoying domain. Just remember the techniques we did in class!
