Find an approximate solution to the pendulum problem such that d2 theta /dt2 +g/l theta = 0. Use an approximate solver in matlab to find the solution to the exact equation d2 theta/dt2 +g/l * sin( theta) = 0. Compare the two solutions when the initial angle is 10, 30, and 90. Find a way to quantify the difference. One approximate method for solving differential equations is Runge-Kutta, which in Matlab goes by the name ode45. I have made a...
