If z = r(cosθ + i*sinθ) is a complex number and n is a positive integer, then z^n = [r(cosθ + i*sinθ)]^n z^n = r^n(cosnθ + i*sinnθ) Nth Root of a Complex Number For a positive integer n, the complex number z = r(cosθ + i*sinθ) has exactly n distinct nth roots given by nth root of r[cos(θ + 2πk)/n + i*sin(θ + 2πk)/n] where k = 0, 1 ...
Example 1: The equation of a circle is given as x 2 + y 2 = 49. Using precalculus, find its radius. Solution: The equation of a circle is given as (x − h) 2 + (y − k) 2 = r 2. The given equation can be written as (x − 0) 2 + (y − 0) 2 = 7 2 where (0, 0) is the center and 7 is the length of the radius. Answer: Radius = 7
