Just as before, one can calculate the uncertainty in the volume by adding the percentage uncertainties in each quantity: ... If one has more than a few points on a graph, one should calculate the uncertainty in the slope as follows. In the picture below, the data points are shown by small, filled, black circles;

To calculate an overall uncertainty for the emission estimate for each source category, the parameter uncertainties determined above for each source of uncertainty associated with the emission estimate can be combined using a sum of squares approach.20 This approach is valid as long as ... c = overall percent uncertainty;

So, in order to calculate the percent uncertainty in Delta Cotangent Phi, you must first determine the absolute values for the uncertainty in the cotangent of phi 1 and phi 2. To do this, you pull the percent uncertainty in cotangent phi 2 off of the graph and multiply by the uncertainty in phi 2, same as you did in...

It is customary to calculate the percent by dividing the discrepancy by the more reliable quantity (then, of course, multiplying by 100). However, if the discrepancy is only a few percent, it makes no ... But when expressing final results, it is often meaningful to express the relative uncertainty as a percent.
