How do yoHow could you derive formula for uncertainty g?

&g = (&g/&h)&h + (&g/&v)&v + (&g/&R)*&R, let & = sign for uncertainty ( i don't know the actual sign used)

outside each parenthesis, there are absolute power sign.

This is a problem for my physics class and i am stuck and no longer able to make further progress.

my problem is to keep making substitutions until &g is written in terms of g and the relative uncertainties of h, v, and R.

g = (2h*v^2) / R^2 equation for gravity.
