If you choose to fill in the blanks, you can give up. It's really abnormal. I really want to do it. I suggest you buy a special fill-in-the-blank training program, which is generally related to functions or conic curves. Actually, I really think it's normal that you can't do it I'm afraid it took a lot of time to calculate those two questions, but there is still no clue and no deviation. It is better to give up decisively and buy some time for the following questions.

The big question, er, I don't know which province you are from, but the finale question should be derivative and conic, right? Make sure you get the first score for both questions. It is really not difficult to score the first question, and the concept of the textbook is clear enough. As for the second question, I suggest that the landlord pick a question and stick to it. If you are sensitive to graphics and have good computing power, you can focus on conic curves. Of course, it is not easy to get full marks in that exam ... the derivative is relatively fast and the question type is relatively fixed. You can take a look at the derivative problems in your province in recent years.

I hope it will help the landlord.
