举一反三
- 求不定积分[img=115x46]17da65382f8e1b9.png[/img]; ( ) A: x - (5*log(x + 1))/4 - (3*log(x - 3)) B: (5*log(x + 1))/4 - (3*log(x - 3)) C: x - (5*log(x + 1))/4 - (3*log(x - 3))/4 D: (5*log(x + 1))/4 - (3*log(x - 3))/4
- 假设原始问题为: max z=2x 1 -x 2 +3x 3 -2x 4 s.t. x 1 +3x 2 - 2x 3 + x 4 ≤12 -2x 1 + x 2 -3x 4 ≥8 3x 1 - 4x 2 +5x 3 - x 4 = 15 x 1 ≥0, x 2 :Free, x 3 ≤0, x 4 ≥0 则对偶问题中约束条件及决策变量的符号依次为: min y=12w 1 +8w 2 +15w 3 s.t. w 1 - 2w 2 + 3w 3 ( ) 2 3w 1 + w 2 - 4w 3 ( ) -1 -2w 1 +5w 3 ≤3 w 1 - 3w 2 - w 3 ≥-2 w 1 () 0,w 2 () 0, w 3 :Free
