Physics Uncertainty Question???? 1. The problem statement, all variables and given/known data I have Vy = 0.125tan(54) = 0.17204. I have to find the uncertainty of Vy Where 0.125 = A and tan(54) = B uncertainty of A (0.125) = 0.0005 uncertainty of B (54 degrees) = 0.5degrees 2. Relevant equations Uncertainty for Multiplication = uncertainty of Vy/Vy = uncertainty of A/A + uncertainty of B/B 3. The attempt at a solution Setup: uncertainty of Vy/0.17204 = 0.0005/0.125 + 0.5/tan(54) My problem is the tangent part: (0.5/tan(54)). do i do that for uncertainty or do i do tan(0.5)/tan(54)??
