This math problem written by Shen Wei is considered to be very difficult and involves profound knowledge points. This question requires candidates to use profound mathematical theories and skills, including mastering functions, limits and derivatives. And the ability to think independently and solve problems innovatively. Therefore, the students who can answer this question correctly have a high level and can be considered as mathematical geniuses.

First of all, this shows that China education has trained a large number of mathematics talents. In China, mathematics has always been regarded as one of the most important subjects, and educational institutions and parents also attach great importance to children's mathematics learning. So in such an environment, many students are excellent and good at mathematical thinking. This also provides talent support for China's future scientific and technological innovation and economic development.

Secondly, it also shows that for math lovers, the convenience brought by the network age can not be ignored. On the Internet, there are many excellent math forums, blogs and video courses, which can provide more in-depth and extensive math knowledge. At the same time, the network also allows some excellent mathematicians and critics to impart their mathematical knowledge and skills to the majority of mathematics lovers through their own platforms or social networks. This provides many resources and opportunities for students' mathematics learning and improvement.

Learning mathematics well requires certain methods and skills. Here are some learning methods:

1, based on foundation: Mathematics has many basic concepts, including algebra and geometry in junior high school, calculus and mathematical analysis in senior high school, etc. Therefore, it is very important to master the basic knowledge of mathematics.

2. Pay attention to practice: Mathematics is a subject that needs both practice and understanding. In the process of practice, you will find different types of problems and solutions, which can gradually improve your problem-solving ability.

3. Think more and pay attention to divergent thinking: Learning mathematics requires divergent thinking to discover the laws behind problems. At the same time, don't stop at the solutions given in the book, but dare to try different ideas and methods.

4. Practical application: Mathematics has many applications in reality, such as finance, logistics, statistics, computer programming and so on. Mathematical knowledge can be more integrated into life through the use of real scenes.

5. Cultivation of self-confidence: When learning mathematics, we should always be confident and be able to overcome those seemingly difficult mathematical problems, which often requires courage and perseverance, and believe that we can do it.

In a word, mathematics needs to pay attention to the cultivation of foundation, practice, thinking, practice and self-confidence. Knowing and following these methods and skills will make it easier to learn and master mathematics.
