Blue colour is the step
Black colour is explanation
If have any enquiries, just drop me a msg.
Hope this helps.
Note: if this kind of question scares u, it is just because you are not familiar with trigo. So, dun be afraid. You just need to:
1. List out all the rules of trigonometry and familiarise urself with them.
2. Practise, so that when u see them (eg. Cot 2x), u can immediately relate it to the answer (cos 2x /sin 2x)
Jia you! :)
