can anyone verify that the equations on the following page, http://nsr.f2o.org/equations.htm [Broken] are corretly solved. The equations are used to find the uncertainity in the calculation of acceleration in my physics lab. The uncertinty (delta a) would be the sum of all of the four equations, which appear correct.(adsbygoogle = window.adsbygoogle || []).push({});

However, the last equation, solves for the uncertainty in g (delta g) which is gravity...I'm not sure how should I solve it using partial derivatives, on the bottom it has what h_21 and x_12 should be...any help would be much appreciated..thank you!
