Generally, the first question will make you ask some simple questions, and you can get the answer as long as you set the formula. Most people will find the latter question difficult. I think the main problem is that there are too few questions, and I can't figure out what kind of questions this is at once in my mind.
Do more questions and choose 1-2 excerpts of different questions in the notebook. Review these questions carefully when reviewing for the last time before the exam.
Secondly, it is also very important that analyzing geometry requires a lot of calculations and requires great care. Some people can do problems, but they appear in calculation errors.
If you can't do it with analytic geometry and the topic doesn't require coordinates, you can also try to prove it intuitively.
I also came from the college entrance examination. I hope you can successfully enter a satisfactory university.
