    鲜儿13484302681: 线性代数问题若A与B相似,则det(A+I)=det(B+I)吗?为什么? -
    35919钮肃 :[答案] 相似矩阵的特征值相同 所以A与B的特征值相同 所以A+I与B+I的特征值相同 而矩阵的行列式等于其全部特征值之积 所以 det(A+I)=det(B+I).

    鲜儿13484302681: 已知复数z=a+bi,且a^2 - (i - 1)a+3b+2i=0,求复数z -
    35919钮肃 : a^2-(i-1)a+3b+2i=a^2-ai+a+3b+2i=(a^2+a+3b)+(2-a)i=02-a=0,a=2,a^2+a+3b=6+3b=0,b=-2,z=2-2i.

    鲜儿13484302681: 已知(a+2i)/i=b+i i为虚数单位 a+b=? -
    35919钮肃 : (a+2i)/i =(ai-2)/(-1) =2-ai =b+i 所以a=-1,b=2 a+b=1

    鲜儿13484302681: 1/ab+1/(a+1)(b+1)+1/(a+2)(b+2)+...+1/(a+2003)(b+2003) -
    35919钮肃 :[答案] 1/(a+i)(b+i)=1/(b-a)*[1/(a+i)-1/(b+i)] 所以∑1/(a+i)(b+i)=1/(b-a)*[∑1/(a+i)-∑1/(b+i)] 把能抵消的抵消.

    鲜儿13484302681: 高中数学.1 - a - bi=(1+a+bi)i整理,得 (a - b - 1)+(a+b+1)i=0.这个结果 -
    35919钮肃 : i的平方等于-10=(1+a+bi)i-1+a+bi=i+ai-b-1+a+bi=(a-b-1)+(a+b+1)i

    鲜儿13484302681: 数学题:1/ab+1/(a+1)(b+1)+1/(a+2)(b+2)+…+1/(a+2007)(b+2007)的值是?
    35919钮肃 : 1/(a+i)(b+i)=1/(b-a)*[1/(a+i)-1/(b+i)] 所以∑1/(a+i)(b+i)=1/(b-a)*[∑1/(a+i)-∑1/(b+i)] 可以去掉的都去掉

    鲜儿13484302681: 已知复数z是方程x²+2x+2=0的解 且Imz>0,若a/z+z的共轭=b+i 期中a,b为实数,i为叙述单位 Imz表示z的求复数w=a+bi的摸 -
    35919钮肃 :[答案] 方程可变型为(x+1)²=-1 所以z= -1+i 或 -1-i Im z >0,所以z=-1+i a/(-1+i) -1+i=b-i a/(-1+i)=b+1-2i a=(-1+i)(b+1-2i)=1-b+(b+3)i 因为a,b为实数,所以a=1-b,b+3=0 a=4,b=-3 所以w的模为5

    35919钮肃 :[答案] 证明:(d-a)/(d-g)=[(e+f+1)-(b+c+1)]/[(e+f+1)-(h+i+1)]=[(e-b)+(f-c)]/[(e-h)+(f-i)]由合比定理(a/b=c/d==>a/b=(a+c)/(b+d))得(d-a)/(d-g)=[(d-a)+(e-b)+(f-c)]/[(d-g)+(e-h)+(f-i)]设上式值为m,即(d-a)/(...

    35919钮肃 : 少了条件,这是因式分解的题目: abc+ab+ac+bc+a+b+c+1 =abc+ac+bc+c+ab+a+b+1 =c(ab+a+b+1)+ab+a+b+1 =(ab+a+b+1)(c+1) =(a+1)(b+1)(c+1) 题目已知abc+ab+ac+bc+a+b+c=230 那么(a+1)(b+1)(c+1)=230+1=231=11...

    鲜儿13484302681: a+2i/i=b+i(a,b属于R),其中i是虚数单位,a+b= -
    35919钮肃 : a+2i/i=a/i+2=ai/(-1)+2=2-ai=b+i 所以b=2,a=-1 a+b=1
