|X/i^2|

|X/i^2| X=[X;fliplr(x(i:2*N+i))] I 2X--4 I=6 ( I 绝对值符号) I X--2 I--4=0 ( I 绝对值符号) 为什么(2-3i)x(1+i)=5-i （x-1-√2i)(x-1+√2i)(x-2+√3i)(x-2-√3i) 高中数学题|X/i^2| 虚数 化简i^(7x+ 2)还有i^(6x-1),i^(14x-11) IaI有非负性,也有最小值0.试讨论:若x为有理数,I x I+I X-2 I+I X-3 I有没有最小值 |X+i| |x-i| (1+2i)(x+yi)=4+3i (x-2y)+(y+2x)i=4+3i 已知2＜x＜3,那么I x-根号2 I+I x-根号10 I=? I 1 3 0 I I 7 I I 0 1 -1 I X= I 2 I求X.大哥大姐,用矩阵的初等变换写~I 2 1 5 I I 4 I fortran程序,subroutine solvereal::i,x,y,mreal::h(i),d(i),a(i),dy(i)h(i)=(1+2*(x-a(i))/(a(i+1)-a(i)))*(((x-a(i+1))/(a(i)-a(i+1)))**2)d(i)=(((x-a(i+1))/(a(i)-a(i+1)))**2)*(x-a(i))m=y(i)*h(i)+dy(i)*d(i)end subroutine solveprogram mainreal::i,sreal::a( 已知(x/1-i)+(y/1-2i)=5/1-3i求x+y int x=20; int i=2; while(i 解I3x-2I-Ix+1I=x+2132
