First, make clear the purpose of the notes. Mathematics is a very logical subject, so the purpose of taking notes is to help you understand and master the logical relationship of mathematical knowledge, rather than simply copying the contents of textbooks.
Secondly, choose the appropriate note-taking tool. You can choose traditional paper notebooks or electronic note-taking software, such as OneNote and Evernote. Which tool to choose depends mainly on your habits and preferences.
Third, make the structure and format of notes. Generally speaking, math notes can be divided into three parts: concept definition, formula theorem and example analysis. In the concept definition section, you need to record the definition and nature of each concept; In the formula theorem section, you need to record the derivation process and application conditions of each formula or theorem; In the part of example analysis, you need to record the steps and ideas of solving each example.
Then, review your notes regularly. Mastering mathematical knowledge requires a lot of repetition and practice, so it is necessary to review your notes regularly to deepen your understanding and memory of knowledge.
Finally, constantly optimize your notes. You can constantly adjust the content and structure of notes according to the progress and effect of learning, so as to make them more in line with your own learning needs.
Generally speaking, taking math notes in senior three is a continuous process, which requires you to constantly think, summarize and improve. Only in this way can you really benefit from your notes and improve your math learning effect.
