[數撚圍爐區] 上世做錯事, 今世讀數學

想問下

搵一個multivariable function 嘅 max/min

一開始要set佢啲partial derivatives =0

其實啫係equivalent to set ∇f = 0

想問下geometrically 點解想佢枝gradient = zero vector

其實個geometric meaning同一維基本上一樣

各位大佬 b應該點做

用a, 將個system combine做一條式

Sydney PM UG中

快啲過嚟睇文

利申: 見到咁多proof唔想睇

cu 數撚lm

讀到想喊

cu 而家好似開左條 data science stream?

其實我淨係預啲人睇點解Dirichlet諗到個conjecture

proof就算把啦

係
不過我year five 啦, 讀一科畢業就算

proof 我會想認認真真拎本書望或者叫人開student seminar講算

巴打year幾？ 咩u

但係唔講proof又好似冇咗開post嘅意義

我唔係嚟講故仔㗎

話說我呢排抽起條根睇elements, 我想講點解古希臘人會咁撚醒
愈睇就愈覺得慚愧

其實好多破舊的人都好勁, 好多idea都好似係石頭爆出黎咁

我諗緊點繼續講我的故仔

唔係爛咗尾喇咩

lm

未
因爲我搵唔番堆花生無貨
一係就skip左堆花生直入Abel Ruffini

又或者直落Galois group of polynomials (and its prerequisite)

開Year 3 Usyd
因為第二個 Sem入學成日都係跳Prereq之後再讀返

我都係yr3 first semester
我都有D yr1科同dse overlap,等遲D先讀.
