f(z)=1/(z^2+5z+6)在z=0的幂级数展开式的收敛半径为
f(z)=1/(z^2+5z+6)在z=0的幂级数展开式的收敛半径为
f(z)=1/(z^2+5z+6)在z=0的幂级数展开式的收敛半径为
f(z)=1/(z^2+5z+6)
=1/(z+2)-1/(z+3)
=(1/2)/(1+z/2)-(1/3)/(1+z/3)
=(1/2)∑(n=0,+∞)(-z/2)^n-(1/3)∑(n=0,+∞)(-z/3)^n
=∑(n=0,+∞)(-1)^n(1/2^(n+1)-1/3^(n+1))z^n |z|
10z-9z-8z-7z-6z-5z-4z-3z-2z+1=?(z是平方,即2次方)
f(z)=1/(z^2+5z+6)在z=0的幂级数展开式的收敛半径为
F(Z)=1/(Z-1)(z-2) 在Z=1处的泰勒展开式
f(Z)=1/z(z+1)(z+4)在2
将函数f(z)= 1/[(z-1)(z-2)]在|z|
将函数f(z)= 1/[(z-1)(z-2)]在|z|
把F(z)=1/z(z-1)在1
f'(z)=(z+1)'(2-z)+(z+1)(2-z)'如何计算
求函数f(z)=z/(z-1)(z+3)^2在z=1处的留数.
f(z)=z^2/{(z^2+1)*(z^2+9)}求Res(z=i)f(z)和Res(z=3i)f(z)
设=2/(1-根3i),z^6-z^5+3z^4-2z^3+6z^2-5z+3,求值,设z=2/(1-根3i),z^6-z^5+3z^4-2z^3+6z^2-5z+3,求值,注i不是在根号裹
(2)f(z)=z^2/(z^2+1)(z^2+9),求Resf(z)(z=i)和Resf(z)(z=3i)
f(z)=z^2/(z^2+1)(z^2+9),求Resf(z)(z=i)和Resf(z)(z=3i)
函数f(z)=1/z(1+1/(z+1)+1/(z+1)^2+···+1/(z+1)^5)在点 z=0处留数我求的1 答案6
已知z=根号3i+1/2 ,则z+2z^2+3z^3+4z^4+5z^5+6z^6=?
已知复数z满足|z|=1且z*z+1/z+2z
求Y(Z)=Z(Z+2)/(3Z-7)(Z+1)的z反变换
f(z)=2z+z'-3i f(z'+i)=6-3i,则f(-z)=?z',z是复数!
