Trigonometric Form of a Complex Number
... In Section 2.4, you learned how to add, subtract, multiply, and divide complex numbers. To work effectively with powers and roots of complex numbers, it is helpful to write complex numbers in trigonometric form. In Figure 6.46, consider the nonzero complex number a bi. By letting be the angle fr ...
