WebWhat are complex numbers? In calculus we used the real number system, R; we describe it as the points on a line. However, for some purposes — e.g., polynomials and differential equations — we need more numbers. The complex number system, C, can be described as the points on a plane. Of course, you’ve worked with points on a plane before. WebThe two numbers, 1 = (1;0) and i = (0;1) play a special role. They form a basis in the vector space, so that each complex number can be represented in a unique way as [we start using the notation (x;0) · x] (x;y) = x+iy : (3) ƒ Terminology: The number i is called imaginary unity. For the complex number z = (x;y), the real umbers x and y are ...
