Evaluate the formula in equation (1) for the following values: L = 0.400 m, g = 9.798 m/s2, and θ = 15 degrees. Now, evaluate the same formula three more times, each time varying one of the three parameters L, g, and θ (and only one) by +1% of the given value. In each case, what is the percentage change of the final result for v?
