Appendix F: Complex Numbers
... To work effectively with powers and roots of complex numbers, it is helpful to write complex numbers in trigonometric form. In Figure F.2, consider the nonzero complex number a + bi. By letting θ be the angle from the positive real axis (measured counterclockwise) to the line segment connecting the ...
