5.3 Complex Numbers and Complex Arithmetic cont.
A complex number manifests itself in two forms¾and consists of two numbers (per form) and presents itself as a vector in the complex plane as shown below
C = a + jb (Rectangular form)
where j = (-1)1/2, a = Re(C) = C cosq , b = Im(C) = C sinq C = (a2 + b2)1/2 and q = tan-1(b/a)
C = C ejq = C /q (Polar form)
