Unformatted text preview: δf directly, but rather are written in a way that is easier to remember but requires that you solve the expressions for δf to determine the uncertainty that you will quote in the calculated quantity. These rules can be applied in turn on more complicated functions. For example the uncertainty in a function that involves both the sum and product of measured quantities h ( a,b,c ) = a × b + c can be determined by ﬁrst ﬁnding the uncertainty in the individual components, i.e. ﬁnd δg ( a,b ) for g ( a,b ) = a × b using formula (2) and then rewrite h as h ( g,c ) = g + c and apply formula (1). Practice Consider measurements of the width w and length l of a piece of paper used to calculated the area of the paper using A = w × l . 14...
