The figure below shows a pendulum with length L that makes a maximum angle with the vertical. Using Newton's second law, it can be shown that the period 7 (the time for one complete swing) is given by dx T=4 Jo √1-k² sin²(x)' (2%) and where k sin and g is the acceleration due to gravity. If L = 3 m and 8 = 42°, use Simpson's rule with n = 10 to find the period (in s). (Use g = 9.8 m/s². Round your answer to five decimal places.)
