Finding the Roots of a Complex NumberVideos, worksheets, games and acivities to help PreCalculus students learn how to find the roots of a complex number.
Finding the Roots of a Complex Number : We can use DeMoivre's Theorem to calculate complex number roots. In many cases, these methods for calculating complex number roots can be useful, but for higher powers we should know the general four-step guide for calculatingcomplex number roots. In order to use DeMoivre's Theorem to find complex number roots we should have an understanding of thetrigonometric form of complex numbers.
More Roots of Complex Numbers : We can use a simple four-step guide to help us find complex roots, or the nth roots of complex numbers. These guidelines simplify for us the process of using DeMoivre's Theorem to find complex roots. This method for finding complex roots uses thetrigonometric form and so we should understand how to convert from rectangular to trigonometric form and from trigonometric to rectangular form.
