In this case, find the stationary points for the function f(x,y) = x^2 - y^2,
subject to constraint (x-4)^2 - y^2 = 1,Also identify the local minimum,maximum
,or neither of both.
我想請問一下，算出來極值點為 (5,0) 跟 (3,0)
為什麼 local minimum = 25,為(5,0)這點，local maximum = 9,為(3,0)這點
原因是為什麼？感謝

1F：推 a016258:都是 local max ? 114.42.179.153 06/18 01:51
