WebBy the way, the whole analysis is nonsense unless the Taylor series actually converges to f; as an example, consider the variance of f ( X) where X is, say, uniform on [ − 1, 1] and f ( x) = { e − x − 2 x ≠ 0 0 x = 0. The Taylor series for this function is the zero polynomial, but you wouldn't want to claim that f ( X) had no variance. : ( Share WebThis fact can be derived by starting with the Taylor series for a function of 2 variables f ( t, x) = f ( a, b) + f t ( a, b) ( t − a) + f x ( a, b) ( x − b)... as I gave in my question. Then consider f ( t, x) − f ( a, b) = f t ( a, b) ( t − a) + f x ( a, b) ( x − b)... as a and b approach t and x respectively.
