[SOLVED] Error Calculation 1. The problem statement, all variables and given/known data A force 500nt is measured with a possible error of 1nt. Its component in a direction 60 deg away from its lnie of action is required. Where the angle is subject to an error of .5 deg. What is the largest possible error in the component? 2. Relevant equations 3. The attempt at a solution I was thinking 1/500 + .5/60 would bring the percentage and then if I multiply % * 500 I would get the amount of "nt"s (what's an nt, a newton?) however that gives a result that is a little too large. I would imagine my problem lies with the angle.. do I need to do something special with it?
