The sum of two nonnegative numbers is 36. Find these numbers if the first plus the square of the second is a maximum. 我連題目都看不是很懂 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 203.68.108.148

推 chynlin:兩正數和36，求第一數加第二數平方的max 61.216.148.136 12/04 00:00

→ chynlin:意即若x,y>0 x+y=36 求x+y^2最大值 61.216.148.136 12/04 00:02

→ chynlin:時， x、y=? 61.216.148.136 12/04 00:06

→ chynlin:自己解釋後覺得怪怪的，有沒有哪位要CHECK 61.216.148.136 12/04 00:36

→ betray911015:可以只令一個變數嗎? 203.68.108.148 12/04 08:53
