若f(z+i)=z-3i,则f(2i)=____,/f(2i)+1/=_____.拜托!
若f(z+i)=z-3i,则f(2i)=____,/f(2i)+1/=_____.
拜托!
若f(z+i)=z-3i,则f(2i)=____,/f(2i)+1/=_____.拜托!
f(z+i)=z-3i
z=i
f(i+i)=f(2i)=i-3i=-2i
f(2i)=-2i
|f(2i)+1|=|1-2i|=√[1²+(-2)²]=√5
|f(2i)+1|=√5
f(z)=2z+z'-3i f(z'+i)=6-3i,则f(-z)=?z',z是复数!
已知f(z+i)=3z-2i,则f(i)=
已知f(z+i)=z+2z-2i,则f(i)=?
f(z)=z^2/{(z^2+1)*(z^2+9)}求Res(z=i)f(z)和Res(z=3i)f(z)
若z的共轭复数为z f(z+i)=z+2i则 f(3+2i)=
已知f(z)=2z+z^2+(1+i),则f(i)的值是
已知f(z)=2z+z²+(1+i)则f(i)的值是
i为虚数单位,若复数Z满足f(z+i)=z-3i,则|f(2i)+1|=?
若f(z+i)=z-3i,则f(2i)=____,/f(2i)+1/=_____.拜托!
f(z)=2z+z的共轭-3i,f(z的共轭+i)=6-3i,试求f(-z)
f(z)=2z+(共轭z)-3i,f(z0共轭+i)=6-3i,求f(-z0)注:共轭z表示z的共轭复数
f(z+i)=3z-2i.则f(i)=还有为什么要等于零
若复数z满足f(1-z)=2z-i,求(24-7i)f(1-i)的平方根
(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)
f(z共轭复数)=z+5i,则f(3+i)=
f(z)=2z+z'-3i f(z'+i)=6-3i,则f(-z)=?我知道答案是-6-4i,大概过程我也明白,但没算明白,
若z∈C且/z/=1,则f(z)=/z+3+4i/的最大值是急
