This website was designed for some time MA1102 Calculus course at NUS. Some of the materials are still found here. The site will be reorganised into a self paced learning and study guide. The guides for each of the tutorial are invaluable for study. Together with my textbook, it forms an integral part of a study module. The additional material and promptings are now on the web. In due course the lectures will be posted here as webcast through power point. The lab sessions are not included. There is plan to include this as visualisation plays a great deal in forming ideas and concepts. Of course there is the added avenue of experimentation and exploration. The software used is DERIVE . But the material could well be adapted for other CAS.
