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^(aj) $ = = cos a+isin a
