谢谢谢谢，不过ma3111的lecturer在course description 里放了句话，Dear Students, MA3111 Complex Variables is a rigorous mathematical module. Please do NOT take this module if you feel that Linear Algebra 2 is too difficult for you. If you take this module, please be prepared to put in your big effort!! Your Lecturer: Assoc Prof Zhang D Q 吓得我都不敢选了。。。
