complex number A number of the form a+bi,where a and b are real numbers and i2= -1 ( or equivalently, i = √-1 ). A complex number is often denoted by a single letter, usually z, we write z=a+bi,where a = Re z(read: "the real part of z") and b= Im z("the ...

foundation, it is the real-world experiences that truly shape us. Do not fear if your journey takes an unexpected turn. Just learn from them, and always remember that every experience, whether in a classroom or on a const...
If complex number z satisfies amp(z+i)=(pi)/(4) then minimum value of |z+1-i|+|z-2+3i| is
Substitute x3x3 for uu to calculate the value of zz after the right shift. z2=0−12−i√32z2=0-12-i32These are the complex solutions to u3=iu3=i. z0=1z0=1 z1=−12+i√32z1=-12+i32 z2=−12−i√32z2=-12-i32...
(a)Since-1 +i is a root of 3z³+13z²+az+b=0, then we have 3(-1+i)³+ 13(-1+i)²+a(-1 +i)+b=0(6+ 6i)- 26i-a+ai+b=0(6-a+b)+i(-20+a)= 0By comparing real and imaginary parts, we have6-a+b=0 and -20+a=0a= 20 and b= 14OR: Sin...
