Thanks, your post is really helpful... I don't know how to use latex but I got the final error as 1.36 x 10-4 .. Hopefully I did it right :smile:

Thanks for all your help so far, but I will leave partials to next year calc... Can you guys simplify this for me

ya... I am pretty sure uncertainities are evaluated using partial differentation

Thanks but a very similar formula is given in my lab manual, but I don't know partial differentiation. So, how would i actually evaluate the uncertainty.

Hi, u = (1/(2LS))^2 L = .9810 +/- 0.0005 S = 8.35 +/- 0.15 Can anyone give me the formula to calculate the uncertainity on u.

Cesium 137 decay rate... I am pretty sure its a constant, since its half life is 30 years.

Hello, anyone know a website to find the background rate of Cesium?

Thanks Justin, dextor.

Thanks for the quick reply.. By 0, I mean that there is no uncertainty on time

Hi, I need to find the uncertainty on cos(theta) given: theta = 5 plus/minus 0.1 degrees what is the uncertainty on cos(theta)? [propagation of error] 2) Suppose I measured the time taken by the pendulum to complete one oscillation. So the pendulum moves downward and I start the...

testing... \begin{array}{r l r l} u &= \ln x \quad & dv &= x\,dx \\ du &= \frac{1}{x}\,dx & v &= \frac{1}{2} x^2 \end{array} [tex] \begin{array}{r l r l} sqrt{a_A^2+b_B^2} \end{array} [\tex]

Let me try again http://octaves.uni.cc/user/Untitled1.jpg

Why doesn't the attached imgae showup? Has the webmaster disabled imgaes?

does somebody know how to do this

How do you ge the answer?
