This question is even so I do not have the answer to this question. "Differentiate"
Y= u( a cos u + b cot u)
I used the sum rule. I got u( -sin u + -csc^2u) I have no idea if this is even close to being right. I knew that the derivative of cos was -sinx and the derivative of cot is
-csc^2x I believe.

You are very close just a few mistakes, if you look at the original problem, notice the u out front, this means you need the product rule. Do you know how to do that?

Yeah ! So I plug everything in the parenthesis into the product rule?

I'm sorry, math seriously is not my subject haha calc 1 is my final math class for my major and ill probably never see it again lol.
