uc(y)^2 = sum((df/dxi)^2 * u(xi)^2)
How?
How this is calculated
The general method is first-order propagation of uncertainty. Common operations use the same derivative rule as shortcuts, and formula mode estimates partial derivatives with central finite differences.
Formula: uc(y)^2 = sum((df/dxi)^2 * u(xi)^2)
