It is relatively easy to score such a big question. There are also many big questions that are generally asked, from simple to difficult.

Let me say that solving triangles is a simple problem. Some theorems, such as sine and cosine theorem and complementary angle theorem, are mastered and generally won't lose points. If you can't solve the equation without thinking, then you must re-examine the problem and change your thinking. Generally speaking, it is not difficult, and there will be no trap for liberal arts students. Remember to draw a sketch on the draft to facilitate thinking.

Solid geometry, liberal arts do not need normal vectors, but only conventional methods, which are usually used as auxiliary lines. How? You must be familiar with all kinds of kilometer theorems and proof methods. To be on the safe side, you still have to learn the normal vector. I once said that you should be familiar with the normal vector and not lose points.
There should be no problem with the platitudes in the series.

Functions generally use derivatives and inequalities. The first question is simple, and the last question may be a bit difficult. As long as you clear your mind, know how to start, slowly hold your horses and calculate, there will be results.

Analytic geometry must be familiar with all the characteristics and formulas of ellipse, circle, hyperbola and parabola, and the method of establishing straight lines. Always think of Vieta's theorem, ask a lot of questions, and make sure that you can lose points except the last question.
Because of the limited number of words and the great variability of mathematics, we can only learn from each other and solve problems when we encounter problems.

Finally, writing norms must be standardized, which is the most important thing! ! !
What are the specific normative methods? Understand for yourself.
