| Abstract: |
| Abstract: This article hasmade the further consummation in the teachingmaterial to the dual extreme value of
function’s sufficient condition under the dual quadratic function extreme value’s sufficient condition, has given suf2
ficient condition of binary quadratic function’s extrmum when AC - B2 = 0, thuswhether to take the extreme value
for the dual quadratic function is possible under this situation to make the correct judgment. |
