What is the general content of mathematics in secondary school as a whole? 30

Middle School Math Classic, do you know what is the most important thing in learning math?

Many students are more troubled when learning mathematics in junior high school, because this course is very difficult, and there are many difficulties, many students can be more effective at the beginning of learning, but after a period of time it will become very difficult, so do you know what the junior high school mathematics book is? Let's find out!

Review your notes. Junior high school math book --- review.

In fact, this is because they forget the previous content when learning the latter content, so it will lead to more difficult learning, so they need to use our junior high school math book - review.

In the review of mathematics, we must study the idea of solving the problem and the steps of solving the problem, so that our grades will improve, no matter how the mathematics test questions change, it is inseparable from the most basic theory, so we must establish a mathematical knowledge tree in our minds.

When we review mathematics, we must sort out and review the basic knowledge, mathematics is a step-by-step course, so we have to establish a mathematical knowledge tree, we must first imagine this knowledge tree in the brain, and then find out our own shortcomings, in the targeted review, for the knowledge points that are easy to confuse, to sort out and achieve complete distinction, the most important point is that we should analyze the problem at multiple levels, draw inferences from one another, and focus on our problem-solving ideas.

The review of mathematics should adhere to a principle, that is, the small questions break through the big questions and the big questions are stable, we cannot make a breakthrough in the big questions, but we can do this on the small questions, consciously practice the speed of answering multiple choice questions and fill-in-the-blank questions, of course, the speed is in the correct situation, which will leave a lot of thinking time for the following test questions, and use various methods to solve them.

In the review of mathematics, we must study the idea of solving the problem and the steps of solving the problem, so that our grades will improve, no matter how the change of the mathematics test question is inseparable from the most basic theory, so it is very necessary to establish a mathematical knowledge tree in the mind, which can help you solve the problem more quickly.

Review the knowledge points.

The above is the content of the junior high school mathematics book, when you are struggling to learn, you can review the previous content first, of course, remember the notes before this time can be used to review, which can better help us learn the content of the later stage, and can improve the problem of learning difficulty.

Proof Solution: Because, so. You're a freshman in junior high school, aren't you?! Finally, indicate the formula (which will not be used later) If the topic is long, summarize it at the end (in summary).

The first day of junior high school: number axis; positive and negative numbers; unary and binary equations; polynomials and mononomials; Rational number; symmetrical figures; Simple questions like probability.

The second year of junior high school: square root (irrational number); congruent triangles; one-dimensional quadratic equations and their applications; primary functions (images, analytical); similar triangles; Polygons (with parallelograms and trapezoids at the top). There is also an inverse proportional function that is fast in progress.

Junior 3: Trigonometric Functions; inverse proportional function (how slow it must be discussed); quadratic functions; Round.

It is a person's height to grow to how tall, there are many factors in this situation, external factors and internal factors, if your parents are very tall, the height is relatively high, then your genes may grow your height to a relatively high level, this height is a very normal thing, then there are some many things, acquired factors, for example, you are still very young, you can work hard to exercise, such as stretching your body. Let your body stretch higher, maybe you will grow taller, so much exercise, such as playing basketball, such some sports should also increase your height, I think you are now 16 years old and relatively young, now the height is 1.71 meters, then you still have a long time to grow tall, the probability of growing to 1.75 meters will be very high.

According to the perfect square formula (a+b) = a +2ab+b

Therefore 3x=2*x*(3 2).

You can use vertices, you can't use the axis of symmetry, the axis of symmetry corresponds to the abscissa of the vertex, the maximum and minimum value corresponds to the ordinate of the vertex, you are already in high school, everyone knows in junior high school

The content related to junior high school is: a function --- extended to a series of numbers; quadratic functions; Round. Triangle; the full meaning of trigonometric functions; Probability and statistics.

High School Sets and Logic; functions (including various properties of functions and various specific functions, and disequal inequalities); Space Sakura early three-dimensional geometry; plane analytic geometry; Preliminary Spine Base of Higher Mathematics; Algorithm; Probability and statistics.

1. Pay attention to learning efficiency: Be sure to listen carefully in class. Preview before class, review after class! Be sure to figure out what you won't know in class after class!

2 There is a mistake book (cliché), but there are many students who can't do it! Don't understand what the teacher says in a good class, and record the important knowledge in the book! No, take care of it! Yes, I have time or take a look before the exam!

3. Pay attention to every exam (big test and small test), don't be discouraged if you fail the test, but study the wrong questions of the exam well, and ask what you are wrong.

Just memorize the formula, apply various calculations, and the more you use it, the more you get used to it.

Algebraic: quadratic radicals, unary equations, binary equations, power transport, trigonometric functions, sets, sequences.

Sets: triangles, rectangles, diamonds, circles, polygons, cylinders, cones, analytic geometry, three-dimensional sets.

Elementary plane geometry (congruence, similarity, triangles, parallelograms, circles, rectangles), fundamentals of algebra, fundamentals of functions (one-time functions, inverse functions), equations (one-dimensional one-dimensional equations, one-dimensional quadratic equations), binary systems of linear equations, and fundamentals of mathematical statistics.

High school functions (exponential functions, logarithmic functions, unary quadratic functions, trigonometric functions and monotonicity periodicity of functions have been added, etc.), derivatives basics, inequalities, vectors, logic, mathematical statistics, vectors, complex numbers, space geometry, conic curves.
