He also made seminal contri butions in analytic geometry, complex analysis and the. If a complex number is raised to a noninteger power, the result is multiplevalued see failure of power and logarithm identities. Recall that a consequence of the fundamental theorem of algebra is that a polynomial of degree n has n zeros in the complex number system. Nel caso di potenze con esponente piccolo come ad esempio, e di numeri complessi espressi in forma algebrica, nulla ci vieta di sviluppare i conti a mano. In this application we reexamine our definition of the argument argz of a. Computing positive powers of a complex number example 8. Evaluate powers of complex numbers using demoivres theorem. However, there is still one basic procedure that is missing from the algebra of complex numbers. Fortunately we have demoivres theorem, which gives us a more simple solution to raising complex numbers to a power. Eulers formula it is a mathematical formula used for complex analysis that would establish the basic relationship between trigonometric functions and the exponential mathematical functions.
