Main Article: Complex Plane Complex numbers are often represented on the complex plane, sometimes known as the Argand plane or Argand diagram.In the complex plane, there are a real axis and a perpendicular, imaginary axis.The complex number a + b i a+bi a + b i is graphed on this plane just as the ordered pair (a, b) (a,b) (a, b) would be graphed on the Cartesian coordinate plane. Thus we can say that all real numbers are also complex number with imaginary part zero. These solutions are also called the roots of the polynomial \(x^{3} - 1\). Also, the amount of information in the problem may increase. The conjugate of the complex number \(a + bi\) is the complex number \(a - bi\). 255 Compiled and Solved Problems in Geometry and Trigonometry 5.
