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 $f^* - f_*$.

Thank you for taking the time to explain your answer. It makes sense now. I was confused and thought $ \mathcal O_{Y,y}\rightarrow f_* O_{X,y} $ and $ \mathcal O_{Y,y}\rightarrow O_{X,x} $ were the same. I removed my unfair remark regarding your solution manual. Let me thank you for taking the time to publish your solutions. They have been incredibly helpful in general, especially for someone self-studying like me.
