1. The problem statement, all variables and given/known data 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) 2. Relevant equations theta = inverseSin(Opposite/Hypothenus) 3. 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 !!
