Good evening Candice! Here are my workings for this question. It's a difficult concept to master at first and there are forms to remember. Moreover, the formula is not given in the exam (though we can obtain these formulae from the addition angle formulae which are provided in the exams). Let me know if you need more explanation.

Thank you so much Mr Eric. Yes, this topic is the most challenging to me thus far, I am still struggling to understand and master the concept. Let me try to digest your advised working solution.
Meantime, I am going to upload another question that I can't solve too.
