Questions about the use of high school math problem sets 10

You only need to copy that model, and the solution ideas of some problems in mathematics are basically the same, but there are only some small changes. Some questions are wrong because of miscalculations, so you don't need to copy them, because you found the method. The big question must be copied, the correct answer and process should be written for the wrong question, and the most important thing is to write what you did wrong, because the knowledge points were not memorized, the formula was not remembered, and so on.

Miscalculations don't count, so that when you look at the wrong question, you know why you are wrong and correct it. The wrong question book is very important, before each exam, don't do a lot of questions or anything, it's just repeating, you can just read the wrong question book to make sure you don't understand it clearly.

You don't have to copy the wrong questions, you can argue that you think the typical ones are fine, and you can't make any noises if you copy the wrong questions.

The big questions are not necessarily copied, but you must copy the most typical representative miscalculation in a category, and you don't need to copy these questions, but you should keep them in mind When doing the questions, pay attention to outlining the key words, which will be of great help to you in solving the problem.

The answer is that it must be noted, because if you don't look at it for too long, you will forget what to do, and I only graduated from high school in my third year, and I know this very well.

First of all, you must position yourself and find your weak points. Copying the wrong question set is not the goal, it is the key to remind yourself not to make mistakes by recording the wrong questions, and at the same time record some ingenious methods and ideas for solving the problem. If you copy all the questions, it's too much of a waste of time, so it's better to review other knowledge points.

Wrong question sets are required.

Don't be too thick.,If it's too thick, you'll feel too depressed.,There's no motivation after a long time.,You can buy a bigger book, such as the specification 191mm*257mm (60 pages)It's enough.。

A good way to give the landlord is to write a summary on loose-leaf paper, the specific format can be set by yourself, and then sorted into binders separately. At first, if you don't feel good, take it out and throw it away to avoid breaking the whole book.

This function is not a composite function.

y=e^xx=log1/2(a)

is a composite function.

The function on the problem is not that the independent variable is another function, but that the constant is another function, so the law of same increase and difference subtraction of the composite function cannot be applied.

If the two functions that make up the composite function are both increasing or decreasing, the composite function is increasing, and if one increases and one decreases, the composite function decreases, which is "the same increase and different subtraction".

The mistake is that this is not a composite function. Therefore, there is no such thing as an increase or a difference.

The idea is wrong, you are not a composite function. When looking at the base of an exponential function alone, it is an increasing function.

In fact, during the college entrance examination, this kind of question is the fastest to take a random number. For example, 1 4 satisfies the question, and the other options do not contain 1 4, so choose a

Causal error, you should start from 2 and push forward, it is the condition, not from the front

The value range of the inner function of the composite function is contained in the definition domain of the outer function, the x power of t, t is the inner function, find the increasing interval of the x power of t, t 1, that is, log(, x is greater than 0, so it is a.

It is an exponential function with log1 2 a as the base (generally only the case where the base is greater than 0 and not equal to 1, this problem can get 0.)

To create a set of mistakes, pay attention to the following points:

1. Sorting, analyzing, and classifying the wrong questions made during the usual practice or exam, analyzing the causes of the errors, and clarifying whether it is a mistake in answering the question, or an error in thinking methods, knowledge errors, and calculation errors, which is a key step in establishing a set of wrong questions.

2. Sorting out the wrong questions should be targeted, not all the wrong questions should be sorted out, and for some memorizing errors and some mistakes caused by test-taking skills and skills, they should be corrected on the test paper or homework paper. It is necessary to focus on sorting out the test points at the level of "understanding and application", the knowledge points that are relatively methodical, and easy to make mistakes, and the knowledge points that are easy to block thinking.

3. Pay attention to the accumulation of methods, and the set of mistakes is not a simple correction of mistakes. It is necessary to focus on diagnosing the cause of the wrong question, pay attention to the teacher's analysis and explanation of the wrong question, the introduction of the question, the entry point of the problem, the breakthrough method of thinking, the skills of solving the problem, the standardized steps and summary, etc., and annotate on the side of the wrong question, write out the thinking process when solving the problem, and expose the analysis of the causes and root causes of their mistakes.

4. For the wrong questions in the "Wrong Problem Collection", you must also look up the materials or textbooks, find out the same or related question types, and make answers to ensure that you master this knowledge point, and you can also try to adapt the wrong questions.

5. Bind the "Wrong Question Collection" according to your own style, numbering pages, and it is recommended to bind loose-leaf in order to replace or supplement it in time.

Finally, be sure to make the most of your set of mistakes. Usually, we should not only pay attention to sorting and summarizing in time, but also read more and reflect more; Although each student's "problem set" is different, the advantages of other students' "problem sets" can be used for reference, so you should also pay attention to the communication between each other.

If you don't get good grades, don't make a mistake in the problem book, because there are too many mistakes (that's what our math teacher says about ours), but have a classic example book. The question in this book must cover all the methods of solving the problem. The first class should be selected from the weight of the usual practice, and the teacher must do it several times.

Don't be afraid to remember the methods, ideas, and formulas, and don't remember them if you don't think about them.
