Definition

  • the complex numbers are combinations of both real parts and imaginary parts, denoted i.
  • These can be written a+bi, where a and b are real numbers.

Some Operations

  • $ j^2 = -1 $
  • $ |a+bi| =\sqrt(a^2+b^2) $
  • $ |z| = |\overline z| $ , where z is complex number
  • Euler Equation : $ exp^(ia) $ = = cos a+isin a
