Errors of indirect measurements
Let y be indirectly measured quantity, it is defined as y = f(x1,x2,..., xn). x1,x2,..., xn is defined as the direct measurements. 1. Errors of indirect measurements are defined as
if the functional dependence of investigated quantity is a polynomial. 2. Errors of indirect measurements are defined as
if the functional dependence of investigated quantity, is a monomial and we can define Dy as: 1. If the functional dependence is
Then
2. If functional dependence is
Then
