If your plane geometry is poor, it has little effect; If the analytic geometry is not good, the influence will be greater.

You can learn calculus and make up what you should, without scaring people.

Remember: it is a practical supplement to learn calculus smoothly, not to make up high school mathematics!

2. The thinking of calculus is very different from that of high school. Many students with good grades in high school, when they get to college,

Academic performance has plummeted, and there are still many such students. At the same time, there are still some middle school grades that are inconspicuous.

Some students, however, have soared after they arrived at the university, and there are countless examples of this.

So, you should be vigilant, but don't feel inferior. If you get good grades in high school, college study will be easier, but this is a counterexample.

And many, many more. Calculus is not easy to master, and calculus of ordinary college graduates is basically one.

A little knowledge only involves memorizing a few formulas, but you don't know why.

As long as you study hard, don't use middle school methods to summarize, never! Many students

Even if you make such a mistake, it is a vicious circle, so that it is difficult to make up the exam again and again. You should always feel it.

The learning method is too limited and rigid, and calculus gives you a good supplement to your thinking method. You keep it

Only when there is freshness can there be a sense of accomplishment and pride.

Finally remind two sentences:

1. The mentality of listening to stories with children in their arms Learn calculus: What happened later? What happened afterwards? Then what, what, what?

Keep asking: then what? Then how to do it? then what So what? 、、、、、、、、、、、、

The most taboo and taboo mentality is: ah, what else? Bigger ... It's not over? 、、、

That is to stay hungry!

Middle school teachers like to make you recite, which is the worst teaching method, even among university teachers.

Many such teachers are muddling along. You should be careful, understand, and understanding always comes first. Only the real one

Only when you have a thorough understanding can you learn well.

Ok, if you have any questions, please come and discuss them together. There is no airtight concept of calculus, as long as you have the heart, it is OK.
