Deriving absolute error equation

Click For Summary
SUMMARY

The discussion focuses on deriving the absolute error equation from the formula \(\frac{e}{m} = \frac{2V}{B^{2}R^{2}}\). Participants emphasize the importance of understanding how to handle constants during error propagation. Specifically, when multiplying by a constant, one must add its relative error to the overall calculation. The conversation highlights the necessity of treating \(\frac{e}{m}\) as a single variable for accurate derivation.

Homework Statement


I need to derive an error equation from the following equation...
\frac{e}{m} = \frac{2V}{B^{2}R^{2}}

Homework Equations


Just... basic... derivation rules...

The Attempt at a Solution


I did try, just don't know how to put the stupid attempt in LaTeX...

I'm stuck at the "2V" part because, in our package, there is no description on how to deal with constants. And I was told to treat \frac{e}{m} as a single variable. Thanks, guys :)

If you are dealing with error propagation then where you are multiplying by a constant you add its relative error like anything else ... but of course it's relative error or absolute error for that matter is necessarily 0.
 
Okie. Now I feel stupid at not realizing something so simple. Thanks :)
