In the following, I don't understand how the expression on the LHS equals to the one on the RHS:
("Im" means "imaginary")
Of course if on LHS we cancel out the (1-i) term on the numerator with the one on denominator we get
And if , then the denominator becomes 2. But I can't work out the rest. Any help is appreciated.
If you are going to do problems with imaginary and complex numbers, it would be a really good idea to first learn what "imaginary" and "complex numbers" are.
