Hi there have i got this right if someone could check please? [tex]z=x+\imath{}y[/tex] Find the real and imaginary parts [tex]z+(1/z)[/tex] sub [tex]x+\imath{}y + \frac{1}{x+\imath{}y}[/tex] if we multiply by [tex]x+\imath{}y[/tex] and i get as the real part as [tex]x^2-y^2+1[/tex]. Have i got this right? Thanks in advance
