prove that overbar/(z1 + z2 + .... + zn) = overbar(z1) + overbar(z2) + .... +overbar(zn)
I showed true for n = 2 already
I then assumed true for n = k and wrote out the induction hypothesis
Then of course I need to show true for n = k + 1 and substitute the induction hypothesis in. So I came out with
overbar(z1 + z2 + .... + zn + zn+1) = overbar/(z1 + z2 + .... + zn) + overbar(zn+1)
I know I'm close, and I'm sure it's something simple that I'm missing but I don't know what to do next.
