1. The problem statement, all variables and given/known data So basically I have plotted two variables I measured on a graph, which gives a simple linear relationship, and have found the gradient and standard error of the gradient (1.21251 and 0.03275 respectively). Now my problem is that this gradient is equal to a constant divided by the value I'm trying to calculate i.e G=constant/v so when I express the variable v with its uncertainty how do I calculate this uncertainty in v from knowing the error in G? 2. Relevant equations (2*pi*f)/c = G 3. The attempt at a solution I attempted to find the ratio between the standard error of the gradient and the gradient and then multiply by my value for c, i.e 0.02042/0.03275*c, is this the correct method?
