I really struggle with calculating errors :( I understand what i have to do, find the partial derivative of each variable and multiply it by the error, square it, add up all the others then square root the total. I just seem totally incapable of doing it :( The expression i have to find error on is:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]E = m_{0}c^2 [\sqrt{1+(\frac{RqB}{m_{0}c\tan{\frac{\Theta}{2}}}) ^2} - 1][/tex]

Where R, B and theta all have errors associated with them!! (to find the error on E)

I've been told its possible to break it down one bit at a time, so evalulating the RqB bit i get:

[tex] \sigma = \sqrt{ (B\Delta R)^2 + (R\Delta B)^2}[/tex]

But no idea where to go next :( Any help much appreciated!
