Complex Number Division Math

To divide complex numbers.

Complex number division math. Now consider the following two complex numbers. Z1 4 5i z2 3i z 1 4 5 i z 2 3 i. First find the complex conjugate of the denominator multiply the numerator and denominator by that conjugate and simplify. A b i c d i a c b d i.

Determine the conjugate of the denominator. Given a complex number division express the result as a complex number of the form a bi. Take a simple example. Go back to complex numbers.

A b i c d i ac bd c 2 d 2 bc ad c 2 d 2 i. Given a complex number division express the result as a complex number of the form a bi. Z1 4i z2 2i z1 z2 4i 2i 2 z 1 4 i z 2 2 i z 1 z 2 4 i 2 i 2. The reason for getting rid of the complex parts of the equation in the denominator is because its not easy to divide by complex numbers so to make it a real number which is a whole lot easier to divide by we have to multiply it by a number that will get rid of all the imaginary numbers and a good number to use is the conjugate.
