This calculation must be done in radians. when you have found theta, express it in degrees. 2. using equation -----> T=2pi(L/g)^1/2 (1+1/4sin^2 *theta max/2) determine how large a percentage error is introduced into T if one neglects the correction term when the amplitude of oscillation, thetaMax, is 5 degrees. Repeat for 30 degrees. I have no idea how to even begin, any help would be appreciated! Follow 1 answer 1 Report Abuse Are you sure you want to delete this answer?

Trending Now Mindy Kaling Florida Melbourne Chelsea Clinton Derrick Rose Frontier Airlines Toyota Highlander Paisley Park Online Schools 2016 Crossovers Tim McGraw Answers Best Answer: 1. the number is somewhere around 0.01 radians. Try various numbers in that range until sinθ = 0.95*θ. 2). Evaluate the term sin²(θmax/2) in the equation, for θ = 5º (convert to radians). Then evaluate the term [θmax/2]² The percentage error is one minus the ratio of these two values x 100 sin value = sin²[(5π/180)/2] = 0.00190265 angle value = [(5π/180)/2]² = 0.00190386 error = 0.064% For θ = 20º sin value = sin²[(30π/180)/2] = 0.0669873 angle value = [(30π/180)/2]² = 0.0685389 error = 2.32% You don't have to worry about all the other terms in the formula since when you take the ratio they ca
