1. The problem statement, all variables and given/known data
If fd is the fractional uncertainty on the distance, what is the fractional uncertainty
on the total mass fM? Hint: use our Taylor expansion approximation that (1 +- x) ^a ~ 1 +- ax when x << 1.
The fractional uncertainty in the mass fM will be related to fd in a simple way.


2. Relevant equations
((f^(n) (a))/n!)(x-a)^n


3. The attempt at a solution
Don't really understand this question do i just do a taylor expansion or what
