1. Function:
Function accounts for 15% of the total score in the senior high school entrance examination, especially quadratic function is the key content of the senior high school entrance examination, and it is also a difficult point for many people to learn badly. Generally, it will appear in the last two big questions of the test paper, which may involve some difficult problems such as the image, application, properties, triangle and quadrilateral synthesis of quadratic function.
Students need to understand the concept, properties and images of functions, and can skillfully use functions to solve practical problems. In order to master this difficulty, students need to do more exercises and strengthen their calculation ability and problem-solving skills.
2. Geometry:
Geometry is another difficulty in junior high school mathematics. The study of geometry involves the nature, judgment, classification and proof of graphics, which requires students to have strong spatial imagination and logical thinking ability.
In the exam, geometry questions usually appear in the form of proof questions and calculation questions, which is difficult. In order to overcome this difficulty, students need to do more exercises, strengthen their spatial imagination and logical thinking ability, and master the properties and judgment methods of various geometric figures skillfully.
3. Circle:
Circle is an important content in junior high school mathematics, which involves the nature of circle, the equation of circle, the comprehensive application of circle and triangle, etc. The problem of circle is usually complicated, which requires students to have strong computing ability and logical thinking ability.
In the exam, the problem of circle usually appears in the form of comprehensive questions, which is more difficult. In order to master this difficulty, students need to do more exercises, strengthen their calculation ability and logical thinking ability, and master the properties and equations of circles skillfully.
The most difficult part of junior high school mathematics mainly focuses on function, geometry and circle. If students want to overcome these difficulties, they need to do more exercises and strengthen their computing ability, spatial imagination ability and logical thinking ability. At the same time, students also need to pay attention to classroom learning, understand the teacher's explanation, actively discuss with their classmates and make progress together. Only in this way can we achieve excellent results in junior high school mathematics learning.
