To add two or more complex numbers, first just add the real portions of the numbers together. For example, to simplify the sum of (a+bi) and (c+di), first identify that a and c are the real number portions, and add them together. Symbolically, this will be (a+c). Using actual numbers instead of variables, consider the example of (3+3i) + (5-2i). In dividing complex numbers in a fractional polar form, determine the complex conjugate of the denominator. The complex conjugate of the polar form (9 + 2i) is (9 - 2i). Then, multiply (9 - 2i) with both the numerator and the denominator of the given equation. Upon multiplying, simplify the equation and note that i 2 = -1.Start studying Multiplying and Dividing Rational Expressions. Argument of a Complex Number Calculator.The argument of a complex number is the direction of the number from the origin or the angle to the real axis. Sometimes this function is designated as atan2 (a,b). Please enter the two values a and b of a complex number in the form a+bi, the argument will be calculated.
