    Covariance of two functions for error propagation

    Hi all, I have two functions: X=A-B Y=A+2B I need to calculate the covariance of X and Y in terms of the (known) variances of A and B as part of a propagation of uncertainty calculation to work out the error on a derived quantity Z=X/Y. All I can find information on is how to...
