Compute with Quantities Containing Errors or Uncertainties

 Description Compute with quantities that have errors or uncertainties, such as experimental measurements and known scientific constants.

Enter quantities that have associated errors.

 > $\mathrm{ScientificErrorAnalysis}\left[\mathrm{Quantity}\right]\left({1.552}{,}{0.002}\right)$
 ${\mathrm{Quantity}}{}\left({1.552}{,}{0.002}\right)$ (1)
 > $\mathrm{ScientificErrorAnalysis}\left[\mathrm{Quantity}\right]\left({2.510}{,}{0.01}\right)$
 ${\mathrm{Quantity}}{}\left({2.510}{,}{0.01}\right)$ (2)

Enter a formula using these quantities.

 > $\frac{4{\pi }^{2}}{{2}^{}}$
 $\frac{{4}{}{{\mathrm{π}}}^{{2}}{}{\mathrm{Quantity}}{}\left({1.552}{,}{0.002}\right)}{{{\mathrm{Quantity}}{}\left({2.510}{,}{0.01}\right)}^{{2}}}$ (3)

Compute the derived error of the formula.

 > $\mathrm{combine}\left(,'\mathrm{errors}'\right)$
 ${\mathrm{Quantity}}{}\left({9.725322477}{,}{0.07849949920}\right)$ (4)

Compute the relative error of the formula.

 > $\frac{\mathrm{ScientificErrorAnalysis}\left[\mathrm{GetError}\right]\left(\right)}{\mathrm{ScientificErrorAnalysis}\left[\mathrm{GetValue}\right]\left(\right)}$
 ${0.008071660285}$ (5)
