This booklet is a collection of presentations I wrote when tutoring my students on several topics of calculus, linear algebra and a little bit of probability theory.
微积分部分分享个人一些经验技巧。线性代数及概率论方面则提供一些框架结构。
The author aims to share his personal experience and technique when dealing with calculus. For linear algebra as well as probability theory the author attempts to set some framework for the reader to set up some better perspectives.
