i need help in a quiz

I’m stuck on a Calculus question and need an explanation.

the quiz will be on Thursday 10/1/2020 at 9 am UAE timing approximately 7 hours from the post of the question

the materials will be in Product and Quotient Rules, Derivatives of Trig Functions, and The Chain Rule

in the quiz, ill be sending a picture of the questions and you will be sending the answers immediately because I can’t go back to the previous question so it will one by one.

the quiz will be around 5 questions
