Question

if x=a/b derive an equation for the fractional error in x​

Answer 1

Anwser: If x=a/b is an equation for the fractional error in x,​ we can assume that the two directly measured quantities are X and Y, with errors X and Y respectively.

The measurements X and Y must be independent of each other.

The  is the value of the error divided by the value of the quantity: A /B. The fractional error multiplied by 100 is the . Everything is this section assumes that the error is "small" compared to the value itself, i.e. that the fractional error is much less than one.

For many situations, we can find the error in the result Z using three simple rules....
