Unformatted text preview: f ( a,b,. .. ) = a + b + ... or f ( a,b,. .. ) = a-b-... the resulting uncertainty in f due to each term is found from f a = df da a f b = df db b where for f ( a,b,. .. ) = a b + ... and df da = df db = 1 with the sign depending on if b is being added or subtracted. This gives f a = a and f b = b . When adding these uncorrelated uncertainties using ( f ) 2 = ( f a ) 2 + ( f b ) 2 + ... we get the general expression ( f ) 2 = ( a ) 2 + ( b ) 2 + ... (2.1) Sum and dierence formula for uncertainty 13...
