Exponential Form to Find Complex Roots

Sal solves the problem x^3 = 1 for all real and complex roots using the exponential form of the complex number. He shows how the roots found in the exponential form are the same as those in a more traditional form of a complex number with a real and imaginary part. This is an interesting video that helps one see the patterns of the roots as they are graphed on the Argand diagram.
