Anyone familiar with Xiao Hao knows that the decimal teacher will not advise you to recite, but if you are in your thirties and forties now, the first thing to do is to recite the top. Now, if you follow the teacher around, it is difficult to remember every concept, formula theorem and image mentioned by the teacher at first. After all, some concepts of high school mathematics are still abstract, but Xiao Hao tells you that after you recite it for a period of time, there will be obvious changes.

Requirements: Every conceptual formula theorem image should be memorized. You can ask your deskmate questions, such as functions. You should know the concept of function, what are the related properties of function and what are the concepts of these properties. Now you may not understand, but you must know everything!

2. Back examples

The teacher will talk about some examples in class, and the second step is to recite this example, including the conditions, solutions and solutions of the topic.

Requirements for reaching the standard: you can close the textbook, write down the conditions and solutions of the questions yourself, and memorize the steps! To find the key words in the title, that is, the title eye, that is, the words that appear in the image of the concept formula theorem you recited before, this is the title eye! Because when solving problems, where do our problem-solving ideas come from, that is, from what we have learned!

Note: this step is a little simpler than the previous step, because the topic is concrete rather than abstract, and it is a little easier to recite! But pay attention to the key point, which is the eyes in the example! Don't just remember the numbers inside, otherwise, you won't do it if you change the numbers!

3. Write the context of each step of the sample transformation.

After reciting the example, you can also distinguish the title of the topic and learn the steps to solve the problem. Next, you should mobilize your brain to think! You should write down the formula concepts involved in each step, such as: finding the domain of the function, and you remember the method of finding the domain. When you look for a domain, first of all, the open type under the quadratic root must be greater than or equal to 0, so there is lgx greater than or equal to 0, and because this is a logarithmic function, think about the image of the logarithmic function and find that the x value corresponding to the function value greater than or equal to 0 is the domain of this function!

Requirements: Make every step clear. If you don't know the transformation, you must ask. At this time, you can ignore the quantity and pay attention to the quality! This quality can really be written by yourself!
