    Numerical Analysis Questions

    How would I show that

    (cond f X g)(x) <= (cond f)(x) + (cond g)(x)

    am I right to assume that (cond f)(x)= (X x f(prime)(X))/f(X)

    Also how would I analyze the error propagation in the exponent x^a (x>0)

    1. x is exact and a is subject to a small error
    2. a is exact and x is subject to small error

    Thank you
