R^2 Regression Proof

    I know the components of R2 as in ESS, TSS, RSS.
    I know cov(x,y) = [[itex]\sum[/itex](yi - ybar)(xi - xbar)]/n-1

    But that's as far as I can go, I have come across lowercase r yet or the sample correlation and proofing how they all fit is a bit beyond me so if someone can provide some help that would be great thanks.

    This is not homework.

    The link is difficult to read.

    Sorry about that. Didn't come up in the test so I am all good.
