Approximation of Errors, Linear Approximation Errors

APPROXIMATION OF ERROR -- APPROXIMATION ERROR

Let x be a any physical quantity then ∂x is said to be say error in the present quantity x.or we can also say that ∂x is error which is known as Approximation Error. Now

∂x                                               Absolute Error
(∂x )/x                                         Relative Error
(∂x )/x  ×100                               Percentage Error
