The calculator displays complex number and its conjugate on the complex plane, evaluate complex number absolute value and principal value of the argument . The maximum number of decimal places can be chosen between 0 and 10 In mathematics, the complex conjugate root theorem states that if P is a polynomial in one variable with real coefficients, and a + bi is a root of P with a and b real numbers, then its complex conjugate a − bi is also a root of P. It follows from this (and the fundamental theorem of algebra), that if the degree of a real polynomial is odd, it must have at least one real root. Can be used for calculating or creating new math problems. If you want to find out the possible values, the easiest way is probably to go with De Moivre's formula. Here's my basic explanation.
