ERROR PROPAGATION IN MULTIPLICATION AND DIVISION
If a quantity E = A x B and the result of measurement of A & B is A ± ?Aand B ± ?B then what will be the error ?E in E? Here if we take differentialswe getdE = B dA + A dBDividing by E = AB and changing differentials by `deltas' we get
 
 
?E/E = ?A/A + ?B/B
