常微分方程操作軟體（Mathlets)
課程中，我們會使用一系列稱作“Mathlets”的特編電腦玩具或示例軟體。你有時候會在堂上見到使用，每個習題集包含一個或多個使用Mathlets的習題。每一個Mathlet都有一個關聯的“幫助”檔，它在新視窗打開並給用戶提供指導。
作為d'Arbeloff互動式數學計畫（d'A I M P）一部分，Mathlets開發的資助來自d'Arbeloff麻省理工學院優秀教育基金。Mathlets的設計和開發是和Hubert Hohn合作。獲得授權使用。

Ordinary Differential Equations Manipulatives ("Mathlets")
In the course, we will employ a series of specially written computer toys, or demonstrations, called "Mathlets." You will see them used in lecture occasionally, and each problem set will contain a problem based around one or another of them. Each Mathlet has an associated "Help" file which will open in a new window and provide user instructions.
Funding for the development of the Mathlets was provided by a grant from the The d'Arbeloff Fund for Excellence in MIT Education as part of The d'Arbeloff Interactive Mathematics Project (d'A I M P). The Mathlets were designed and developed in collaboration with Hubert Hohn. Used with permission.
