second order differential equation.
d^2x/dt^2 + 16.085*x = 0, x(0) = pi/6, x'(0) = 0
this is a swinging pendulum problem, where x is the angle the pendulum makes from vertical. The length of the pendulum is 2 and g = 32.17
d^2Theta/dt^2 + g/2*sin(theta) = 0
For small angles x is approximation for sin(x)
