    Can someone confirm if I did this logarithmic differentiation problem correctly?

    Question:
    y = (sin x)^x y' = ?

    My work is attached. I just want to know (a) If my attached work is correct. (b) IF I can do this without using logarithmic differentiation.

    Any input is greatly appreciated!
    Thanks in advance!
