## Homework Statement

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)

## Homework Equations

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 !!
