1. The problem statement, all variables and given/known data I am doing this calculation in my lab: h = sin(24.0°)[(180.0cm)(1m/100cm)] The uncertainty on the angle is ±0.5° and on the length it is also ±0.5cm. How can I go about calculating the uncertainty? If you know the answer, do you mind putting it in terms of a non-calculus student. I googled and found this, but could not understand a word of what they meant: http://www.sosmath.com/CBB/viewtopic.php?t=45581 I'm in more need of a simple formula I can plug numbers into to get the correct uncertainty. The understanding of the math behind it is not as relevant at this time. 2. Relevant equations N/A 3. The attempt at a solution I can get the answer, but not the uncertainty. Here is the answer: h = 0.732m Thanks for your help.
