For Duffing's Equation (Section 8.1, HW # 13 done in class), $y'' + ky + ry^3 = A \cos \omega t$ the behavior of the solutions changes as $r$ changes sign. When $r > 0$, the restoring force $ky + ry^3$ becomes stronger than for the linear spring ($r = 0$). Such a spring is called hard. When $r < 0$, the restoring force becomes weaker than the linear spring and the spring is called soft. Pendulums act like soft springs. Let $k = A = 1$ and $\omega = 10$ with initial conditions $y(0) = 1$ and $y'(0) = 0$. Find the first three nonzero terms in the Taylor Polynomial approximation to the solution for $r = -1$. (Note that this is not the same method as using a power series, please use the method as shown in class for full credit.)
