A complex number has a real part and an imaginary part. The magnitude of a complex number {eq}\displaystyle z =a+ib {/eq} is given by {eq}\displaystyle |z| =\sqrt{a^2+b^2} {/eq} The conjugate of a complex number {eq}\displaystyle z = a+ib {/e...
Let z=x+. Then its conjugate is z=x-.When z=z, then real part and imaginary parts must be equal.Re(z)=Re( z)AndIm(z)=Im( z)Im(z)=-Im(z)2Im(z)=0Im(z)=0It is very clear that, for complex number and its conjugate to be equal, the imaginary part must be zero.When ...
The product of a complex number and its conjugate is a real number.z*z̄ = |z|^2z*z̄ = (3+4i)*(3-4i) = 9-12i+12i+16 = 25|z|^2 = 5^2 = 25Formula in cell D3:=IMPRODUCT(B25,IMCONJUGATE(B25))The image above shows a chart that has a complex number, its complex...
