I'm lost, too. What are you doing? "So" implies that the derivative is somewhere in the middle or near the end of... something... but I don't know what, nor how you go there.

Kindly please reply with clarification, including the full and exact text of the original exercise, the complete instructions, and a clear listing of your efforts so far. Thank you!
