6.2. notes#

The relative error is at most 3.95%, except for \(x=1\) at the moment \(t=\mathrm{0.1s}\) the error is 11%. This error was obtained for the lowest temperature value (\(T=0.004°C\)). This difference is explained by the fact that the error function at this point is 0.025347 and that the uncertainty in calculating the error function is unknown.
