樓主真Chur
不過個post又令我想拎番以前讀 analysis （CUHK MATH 2050 2060）啲野出黎睇
支持高汁post

呢個應該係 4050 
我果陣無到咁深
（我minor 黎架炸 唔係major 唔敢挑戰 real 同 functional）

Functiomal 無咁多 epsilon delta 會開心d
同埋functional 需要linear algebra 同 point set topology 多過 elementary analysis

請問係咪non-continuous function 係咪搵唔到area?
指緊non-continuous 既interval
指緊non-continuous 既interval
好似唔係，只要discontinuous既點足夠少就係riemann integrable
利申：唔識
利申：唔識
Iff set of discontinuity is countable
Set of continuity is of length zero
Countable set 只係 length zero ge 特例
Cantor set 係length zero 但 uncountable

唔係呀，我一開講Riemann integral 果陣個d estimation 用ge function咪discontinuous lor

記錯咗
諗住砍掉重練
其實no one cares 呢條theorem
用處唔大，呢條theorem 只係話太多discontinuities 會令Riemann integral 條橋行唔通
但唔代表用Lebesgue 條橋唔得
有條定理就係話Riemann integrable implies Lebesgue integrable.

又砍？諗住點重練？
諗下有無D咩 intuitive的方法講, 而家太 technical, technical ge部份不如留返比D真係有興趣的人搵本書睇
