Line 54:
a*a*a*a * 2 * 2 * σ[a]^2 / a^2
Take a = 100 ± 2. For a*a I get an error of 282.84, while for a^2 I get 400.00. --[[User:Abu|Abu]] 10:01, 18 August 2011 (UTC)
:Yes, but this is at least in part a bug in the implementation of multiplicative uncertainty. See also: [[Talk:Numeric_error_propagation#What_about_correlations.3F|What about correlations?]] and [[Talk:Numeric_error_propagation#Not_sure_how_to_do_this|Not sure how to do this]]. Since this question is so easy to ask, I am going to explicitly address it in the task description. --[[User:Rdm|Rdm]] 10:38, 18 August 2011 (UTC)
