Complex numbers 8 - using De Moivre for root computations
Listen now
Description
Shows how to solve for cube roots, 4th roots and so on of complex numbers. Makes use of De Moivre's Theorem, but the focus is on a simple presentation style which shows why the result works.
Looks at the computation of square roots using complex number algebra. This uses simple problems to establish an approach to such problem solving which subsequently can be applied to more complex root problems.
