WebComplex number. A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i2 = −1. In mathematics, a complex number is an element of a number system ... WebWe need to find a term by which we can multiply the numerator and the denominator that will eliminate the imaginary portion of the denominator so that we end up with a real number as the denominator. This term is called the complex conjugate of the denominator, which is found by changing the sign of the imaginary part of the complex …

WebMay 30, 2024 · The main goal of finding the quotient of complex numbers is to eliminate the imaginary portion of the denominator. We can use complex conjugates to perform division in the complex number system. If we want to find the quotient of a +bi / c = di where a,b,c, and d are real numbers, we simply multiply the numerator and the denominator by the ... WebDivision of Numbers Having Imaginary Numbers Consider the division of one imaginary number by another. (a+bi) / ( c+di) Multiply both the numerator and denominator by its conjugate pair, and make it real. So, it becomes (a+bi) / ( c+di) = (a+bi) (c-di) / ( c+di) (c-di) = [ (ac+bd)+ i (bc-ad)] / c 2 +d 2. Video Lesson Imaginary Numbers 448 WebAnswer (1 of 6): There can. But it is generally easier to read \frac {3 + 4i}{5} rather than \frac {2+i}{2-i} even though they are equivalent. The standard form is particularly helpful if you … the primitive hare designs
