Notes for High School Mathematics

Preface

A Letter for Readers

Most of you must have read my previous work Notes for Calculus Life Saver. However, I think a “hyper jump” directly from middle school math to advanced math may be a bit hard for some readers. So in order to help some readers——and me of course——I come up with the idea of writing a column that systematically talk about High School Math.

Another stimulation that makes me write this is a teeny tiny test happened just this morning. I was puzzled and confused immediately I got the peper :“Wa-wait! What the hell is the dot product over there? What’s happening when there comes a inverse function or an analytic geometry question just on a middle school paper?”

After I made up my mind to have a thorough review of high school mathematics, I think it may be nice to share my experience and understanding of it with my classmates. So I write this column, I hope you will like it.

Yours sincerely
