Web首先,a=0了,ac=0.ac-b2一定小于零了,没有极值啊.而且讨论a=0很没有意义的,因为x要存在二阶偏导数,导出零只能说明fxx只有一阶导数或没有.关于等于零的,只能自己验证了,而且一般等于零的函数都是很好验证的函数,比如fab：a2+b4和a2+b3之类的.公式不是常有的,在处理1与2时我们用了二元泰勒公式,而它只能帮 ...

WebNov 4, 2007 · Now that we know that fx= 2x+ 3y f (x,y) must equal x^2+ 3xy+ h (y). Then we would have fy= 2x+ h' and fyy= h"= 2 so h, since it is function of y only, is y^2+ cy+ d. Taking those constants of integration to be 0 for simplicity, f (x,y)= x^2+ 3xy+ y^2. That has fxx= fyy= 2> 0 but fxy= 3 so D= fxxfyy- (fxy)^2= 4- 9= -5.
