I have a simple task of measuring the changes in volume (delta V) of water due to rising temperatures. I have trouble combining certain errors. How would one get the error for (V0-V)/V if one already knows the error for V0(volume at start of measurement) and V(measurement of volume). I know how to combine relative and absolute errors when dealing with +,-,*, / I'm assuming I can't just use these rules here since the errors of V-V0 and V are... well related. I would also really appreciate if anyone could also give a link to a good online or downloadable resource which I can use to study and perhaps solve examples of how to calculate and combine errors. Thanks for all your help. :) Sorry for bothering you with such easy problems.
