係-2
我想講大過12其實係pass through f(0) 同f(4)個條直線由0 in 到4既area,因為concave downward所以一定大過or equal 12

自己畫個graph出黎就會到

但係題目就係要你proof mathematically
你咁唔係畫完個graph就講番佢要你proof既野出黎咩

計到囉好冇，我係話畫俾自己睇啊ching
Area below straight line =12

咁我用MVT果度有咩錯

冇錯既。。除左其實中間個part可以唔洗寫。。
應該冇分別既，佢剩係睇有用個part
Ching你個題in abs(f'(x^2)) 點？
成份卷最難

唔係let左u=x^2，再拆兩舊就得喇咩
我覺我最尾果題先最大問題
因為根本唔知會點扣你分

好後悔中學冇讀m2
陣間1012
上次mid term得mean
final mean都唔知有冇

上次mean幾多

聽日PHYS1003 揮手

lixi acct 0 workload no attendance no assignment乜都冇
45% mt 55% final
教又教得少得8課教左

仲要佢話平均佢派多D A range
最正ACCT 2010 lecturer肯定係佢

我連cheat sheet都未整

我都諗過，不過呢個算唔算係by intuition

究竟條題目係乜鳩呀屌

given f is continuous and f(0)=2 f(4)=4
f''<0 for 0≤x≤4

is it ture that integral of f from 0 to 4 >12
好似係除非唔係

given f is continuous and f(0)=2 f(4)=4
f''<0 for 0≤x≤4

is it ture that integral of f from 0 to 4 >12
好似係除非唔係

咁咋

坐左3個鐘就唔係咁講啦

你話你maths 好勁冇野唔識?
有條mc出L錯左 5個options錯到離曬譜 曬左10幾分鐘死諗爛諗又點 快D做下面好過啦
