In this exercise you will familiarize yourself with simple C structures by evaluating polynomials with a complex argument and complex coefficients. As we discussed earlier, polynomials are very important in a wide variety of application areas. Polynomials with a complex argument and complex coefficients cover are a generalization of the real case.
Complex numbers are also very common in electrical circuits problems.
Arithmetic operations can be performed on complex numbers using this formulation. Subtraction and division are defined in a similar way. This is just some of the elegance found in the complex number system. This means if we have such a polynomial, all solutions can be considered complex. Gauss finally proved this in 1849.
