1, unary quadratic equation: This is an important subject in junior three mathematics, which involves how to solve quadratic equation and the properties of its roots. For example, if y=ax? +bx+c (where a, b and c are constants and a≠0), then y is called the quadratic function of X. Quadratic function is one of the core contents of junior high school mathematics.
2. Geometric figures and sense of space: The cultivation of geometric figures and sense of space is an important part of junior three mathematics teaching, which involves the properties and calculation of various figures such as parallelogram, rectangle, diamond and square. Data collection, arrangement and description, this part mainly involves data collection, arrangement, description and analysis, including frequency distribution table and frequency distribution histogram.
3. Proof and reasoning: The math curriculum in Grade Three also focuses on cultivating students' ability of proof and reasoning, which is not only an important thinking skill, but also a key step to solve complex problems. Reasoning is the process of drawing new conclusions based on known facts and rules. Proof is to prove the truth of a proposition through logical reasoning.
Eighth grade learning method
1. Make a reasonable study plan: Make a reasonable study plan according to your own study situation and goals, including daily study time and weekly review plan. And we must persist in implementation and constantly adjust and improve. Make efficient use of class time, listen carefully, take notes and solve problems in time.
2, do more exercises: through a large number of exercises to consolidate the knowledge learned, improve problem-solving ability and application ability. You can choose some classic problem sets or online learning platforms to practice. Reasonable arrangement of extracurricular activities, in addition to study, we should also participate in some extracurricular activities, such as sports, music and art. This can relax the body and mind and improve the learning efficiency.
3. Cultivate good study habits: Develop good study habits, such as finishing homework on time, reviewing regularly, and keeping a clean and tidy learning environment. These habits can help you manage your time better and improve your study. Ask for help and support. Don't be afraid to ask for help and support if you encounter learning difficulties or problems. You can find teachers, classmates or parents to solve the problem.
