T = 4V The figure shows a pendulum with length L that makes a maximum angle @o with the vertical. Using Newton's Second Law, it can be shown that the period T (the time for one complete swing) is given by -TT/2 dx L go 1 - k2 sin2(x) where k = sin(100) and g is the acceleration due to gravity. If L = 2 m and 60 = 46°, use Simpson's Rule with n = 10 to find the...
