How many pages are there in general postgraduate mathematics notes?
1. Copy the basic formula (unnecessary)

Because of my poor personal foundation, I recorded some basic mathematical formulas commonly used in high school on the first page of my notes, which can save me the trouble of searching online when I encounter simple knowledge points and forget the answers.

2. clearly mark the page number

When you think of a knowledge point, don't look around, mark the page number, so that you can mark the page number when you want to quote the knowledge point, and then look at it. For example, if I quote Lagrange's mean value theorem on page 22, I will mark it as p22- La.

3. SD progress

This is to save time in the future. For example, when you look at your notes and find that you have forgotten a knowledge point and want to go back to the online class, you will find that you need to find a knowledge point in a bunch of classes with the same topic, which is very time-consuming, so I will mark it in my notes. For example, this is the content of lesson 0 14, and I will mark it in front.

4. Distinguish between examples and knowledge points

This is to facilitate the unified view of knowledge points, clear at a glance, without scanning examples, saving time.

5. The nature of the distinction theorem definition.

This is also to sort out knowledge points and let yourself find what you want quickly.

6. Mark the key points with pens of other colors.

These are some traces of personal notes. Some people may think it is too much trouble and a waste of time, but I will find it very convenient and labor-saving to put it into use. Of course, these actions are all done when I take notes. I do them while learning. If you have taken a lot of notes, it is meaningless to go back and do it, which is a waste of time.
