# Precentage error watch

1. Hi,

I have done an experiment and plotted my results then found the equation for the line of best fit and was just wondering when im working out the percentage error which value do I use for the actual value the value I got in the experiment or the value given by the equation?

Thanks
2. You'd estimate uncertainties for your data and plot points with error bars (A2) before fitting your line.

What are you trying to find the percentage error of?

The percentage error of a value is given by:

(Error on measured value/measured value)*100.

So it should be the value that you got in the experiment.

wat u do is integrate between 1 and infinity, then find the taylor series around the dirac delta function and then u solve the trivial reimann hypothesis the ur done QED
