The points on the Argand diagram for a complex conjugate have the same horizontal position on the real axis as the original complex number, but opposite vertical positions. lyx. Jan 7, 2021 #6 PeroK. Follow asked Oct 7 '17 at 15:04. serendipity456 serendipity456. Here is the rest of the problem: The conjugate of the product of the two complex numbers is equal to the product of the conjugates of the numbers. Insights Author. Since these complex numbers have imaginary parts, it is not possible to find out the greater complex number between them. The complex conjugate of a complex number is the number with the same real part and the imaginary part equal in magnitude, but are opposite in terms of their signs. The complex conjugate sigma-complex6-2009-1 In this unit we are going to look at a quantity known as the complexconjugate. Let’s find the reciprocal of the complex number z = 4 – 3i.
