we have been doing some error analysis in school, but they were very straight forward for example. Centripetal Acceleration : Fc = 4pi^2 m R / T^2
however, for my project i must find the uncertainty in the angle that i measured.
the angle is formed by a cardboard sitting on pile of books creating a triangle.
Hypothenus = 33cm
Height = Variable ( Changes according to the stack of the book)
please help !! differentiate theta = inverseSin(Opposite/Hypothenus)
theta = inverseSin(Opposite/Hypothenus)
The Attempt at a Solution
well since i measurd these distances with a ruler
the uncertainty for hypothenus would be +- 0.005m (last half digit of a number)
and the uncertainty for heght is the same + - 0.005m (last half dight of a number)
how do i use these to differentiate for one another?
which formurla woudl i use pleaes help !!
