Hello! Here are some suggestions for you:

That's because you despise those too much. I have a problem I am different from a freshman.

I got 28 points in my first math test, so I still know how you feel.

There is no way to do this, but to do the problem crazily, do it crazily in science, and remember it crazily in liberal arts.

I'll tell you why you can't learn well, because the textbooks are too simple now. If you only know the textbook, I think you may know nothing. Is the People's Education Edition where you are? ! If you master the chemistry books taught by others, I guess it will be difficult for you to pass the college entrance examination.

You prepare an error correction book and write down your mistakes. The more you are afraid of making mistakes, the more you have to do it. If you make a mistake, write it in a book and read it over and over again until you can remember the answer at a glance. Then you have succeeded. A weak foundation at first will soon be forgotten. Maybe you will forget all this in the morning and afternoon. I've done this before. I care about what I learn repeatedly. In fact, sometimes you have enough questions, but you really ask yourself.

Trigonometric functions are simple and have vectors. Geometric analysis is more difficult, not the content of senior two. Trigonometric function is very simple. You can conquer it as long as you work hard. It's almost like playing, not bluffing. Really, my previous trigonometric function was so bad that I couldn't even figure out how many sine and cosine values corresponded to how many degrees. At that time, the junior high school teacher asked me to draw triangles, so I barely remembered trigonometric functions.

What exactly should I do? Like I said before, you can do exercises like crazy. There are some things you can hold on to, but you can't. Science can never be learned by memory. You must master the so-called formulas and use them as quickly as your hands and feet, and you will succeed. Let me just give you an example.

3cosx+cos2x+cos3x, if it can't triple the angle, it doesn't matter, if it can't double the angle. . . . Then you are really finished, because cos3x=cos(2x+x), some things are very simple, as long as you can play through it, everything can be very simple.

I'll just talk about how I conquered trigonometric functions. I have made four workbooks, and now I am basically familiar with the triangle problem (except for that inequality, I was lucky enough to read it once). Do more questions and you will. When you get the exercise book, you conquer all the problems. Without loopholes, mathematics is definitely not bad.

At that time, I was not embarrassed to do math. I fell asleep in math class. In the first semester, I almost never heard of mathematics, and the class was very noisy. Besides, the teacher speaks quickly and quietly. No matter how good the teacher is, it's no use whether you listen or not. It's useless if you don't work hard yourself. I do math every day, and I can spend three hours a day alone, which is enough for me. The first time was 28 points, as I said, the second time, but I still failed, more than 70, the third time was more than 90 (three times in the first semester), the second semester, the first time I took the exam 100, and the second time I was close to 100. In short, people are still lazy and can't do anything.

Another point, I emphasize, is not only lazy, but also diligent. The more you use your brain, the more you live. Write the wrong questions in the wrong books. If you can't remember, you can write it again and review it every week.

If you want to test how well you review, do those questions that you find difficult. The more difficult it is, the more difficult it is to face. You may owe too much and feel at a loss. This is everyone's. As long as you grasp the knowledge points, it is actually very easy to learn well. No matter what subject, it is still a matter of mentality. If you treat it negatively, naturally it will treat you negatively, and in the end it will only get worse and better.

In short, everything is under your control. I think you already know what to do. Not much to say, right?

Where there is a will, there is a way. If we cross the rubicon, 120 Qin Guan will belong to Chu after all.

Hard-working people, heaven rewards hard work, and never stops. More than 3,000 armour can swallow Wu.

Wish you success!
