Finding Complex Roots: Can You Trust Your Calculator?
Ciesla, Barbara A.; Watson, John W.
Mathematics Teacher, v99 n5 p366-371 Jan 2006
This article investigates a specific instance when the textbook answer for finding a root of a complex number differed with the answer given by the TI-83. After explaining the reason for the difference the article then expands the definition of the integral root of a complex number to an arbitrary complex power of a complex number.
