linear spaces

tough topic this one... yupz hard time understanding it..

dunno if i should just give up this topic and salvage the others. haha but then beethoven say that if we give up linear spaces and give up complex numbers, we might as well give up further maths entirely. lol...

oh well, 3 hours of beethoven today. one more hour of beethoven tomorrow. spent like 45min doing one question on hypothesis testing. Wah rao... concept so chim one...

oh on a sidenote, stupid tagboard's screwed. Think the entire server went down, can't find it online anymore. So yup gotta find a replacement, so hang in there guys... any suggestions?
