Complex numbers in rectangular form
Web1.4. Division: Rectangular Form. We can use the concept of complex conjugate to give a strategy for dividing two complex numbers, z1 = x1+iy1 z 1 = x 1 + i y 1 and z2 = x2+iy2. z 2 = x 2 + i y 2. The trick is to multiply by the number 1, in a special form that simplifies the denominator to be a real number and turns division into multiplication. WebComplex numbers can be graphed in this complex plane, as shown in FIGURE 46 for the complex number 2 - 3i. Each complex number a + bi determines a unique position vector OP with initial point (0, 0) and terminal point (a, b). NOTE This geometric representation is the reason why a + bi is called the. rectangular form of a complex number ...
