How to solve for complex numbers

WebThe 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. Comment WebSep 16, 2024 · First, convert each number to polar form: z = reiθ and i = 1eiπ / 2. The equation now becomes (reiθ)3 = r3e3iθ = 1eiπ / 2. Therefore, the two equations that we need to solve are r3 = 1 and 3iθ = iπ / 2. Given that r ∈ R and r3 = 1 it follows that r = 1. Solving the second equation is as follows. First divide by i.
