In my exercise book I couldn't find a way to solve what I've typed below (I know for final solutions anyway):
Find Re(w) and Im(w) [where ]:
So we have to write a complex number in a standard form and then extract a real and an imaginary part from there. We work here with the unknown variables ( and ).
My way would be:
If I expand the expression further (i.e. numerator) I don't find a way to write it in a standard form.
However, the final solution is:
Does anybody know the steps leading to the final solution?
Find all solutions to the equation [where ]:
It is a quadratic equation and has a conjugate of complex number in it.
Thanks for help in advance.
