    Trigonometric Derivative Question that I'm getting wrong

    I attached the question in black and the answer in red in the "question & answer.pdf" file. My work is attached in the "mywork.pdf" file.

    Can someone point out what I am doing wrong and tell me the appropriate way to go about it?

    Any help would be greatly appreciated!
    Thanks in advance!
