.
Thus,
And similarly,
Thus,
.
is it true that
??
if so what is the proof?
here is my workin so far.. please verify it thanks.
We know
let c = z - w, so
Now z = c + w,
so
Now let d = - w,
so
subbing in -w for d we get,
subbing in |w| for |d| since they are equal, we get
(i added an extra modulus bracket outside the right hand side at the end of the equation).
End of proof.
Is this correct please? please guide me if i am wrong?
