Question

state Demvoir's Theorem

Answer 1

DeMoivre's theorem is used the find the roots of a complex number for any power n, given that n is an integer. DeMoivre's theorem can be derived from Euler's equation, and is important because it connects trigonometry to complex numbers. For any complex number z (where x represents the real part and i the imaginary part) of the number, and integer n, the following is true: . The expression is often written as cis x, which gives the equation the form . DeMoivre's theorem fails if n is a non-integer...
