AHL HL 1.12
A complex number
is sum sum of a real number a and an imaginary number bi.
We call a the real part of z and b the imaginary part of z:
For example, z=2β3i is a complex number with a real part Re(z)=2 and imaginary part Im(z)=β3.
If two complex numbers are equal, then both their real and imaginary parts are equal:
