Step 1: After getting familiar with the knowledge points in the book, draw a mathematical structure diagram in your mind with the ability of association.

The second step: draw a mathematical mind map and meditate on keywords, routes, etc.

The third step: let the mind map drawn in your mind combine with words. After these three steps, we can easily find the image of mathematical mind map in the brain map, and then observe nature from the image. Therefore, mind mapping is an effective mathematics learning method.

The best systematic summary tool for high school mathematics. Draw the mathematical model and the images of the above problems with mind map, and you will find that the original unclear knowledge system is so simple.
