comment Subsheaf generated by one section is coherent
That's incredibly helpful. It's very simple once you put it this way.

comment Pullback commutes with dual for locally free sheaf of finite rank
Thank you for your answer. The proof in the question uses the projection formula. As I point out in my question, I'm trying to prove this formula, so I cannot use it. The morphism you construct in your answer might work, but frankly I'm getting lost because of the use of the adjunction $f^* - f_*$.
