13) write the expression for the error of quotient of two quantities. |
|
Answer» Error of a product or a quotientWhen TWO quantities are multiplied or divided, the relative error in the RESULT is the sum of the relative ERRORS in the multipliers. Z ± ΔZ = (A ± ΔA) (B ± ΔB) = AB ± B ΔA ± A ΔB ± ΔA ΔB. Dividing LHS by Z and RHS by AB we have, 1 ± (ΔZ/Z) = 1 ± (ΔA/A) ± (ΔB/B) ± (ΔA/A)(ΔB/B). |
