Question 151: Units , Dimensions and Error Analysis

Question

If $Z = {{{A^2}{B^3}} \over {{C^4}}}$, then the relative error in Z will be :

Accepted Answer

$Z = {{{A^2}{B^3}} \over {{C^4}}}$
$	herefore$ ${{\Delta Z} \over Z} = {{2\Delta A} \over A} + 3 	imes {{\Delta B} \over B} + {{4\Delta C} \over C}$

Answer

${{\Delta A} \over A} + {{\Delta B} \over B} + {{\Delta C} \over C}$

Answer

${{2\Delta A} \over A} + {{3\Delta B} \over B} - {{4\Delta C} \over C}$

Answer

${{2\Delta A} \over A} + {{3\Delta B} \over B} + {{4\Delta C} \over C}$

Answer

${{\Delta A} \over A} + {{\Delta B} \over B} - {{\Delta C} \over C}$
