we will describe uc's calculus online, now available to all uc 2022年亚洲世界杯预选赛 through our new cross campus enrollment system as well as to all non matriculated 2022年亚洲世界杯预选赛 including foreign nationals. calculus i for science and engineering 2022年亚洲世界杯预选赛 has been successfully running for over a year and calculus ii since last spring. calculus iii and iv are currently in development. the courses have many components, from introductory welcome lectures, historical enrichment video lectures, online lecture videos (all synchronized with an online interactive e-text originally developed for print by ucla professor jon rogawski), to an online discussion forum platform all accessible via uc's canvas learning management system. we would very much welcome questions and suggestions.
