![**Modeling the Undamped Spring/Mass System Using Differential Equations**
In this lesson, we explore how differential equations can model the behavior of an undamped spring/mass system. This system is governed by the following equation with a nonlinear restoring force \( F(x) \):
\[ m \frac{d^2 x}{d t^2} + F(x) = 0 \]
For this specific system, the given differential equation is:
\[ \frac{d^2 x}{d t^2} + 4x - 16x^3 = 0 \]
### Initial Conditions
To plot the solution curves, we use a numerical solver with the following initial conditions:
1. \( x(0) = 1 \), \( x'(0) = 1 \)
2. \( x(0) = -2 \), \( x'(0) = 2 \)
### Graphs Explanation
#### Graph: \( x(t) \) with \( x(0) = 1 \), \( x'(0) = 1 \)
- **Description**: This plot shows the solution \( x(t) \) for the given initial conditions over time \( t \). The horizontal axis represents time, and the vertical axis represents the position \( x \).
- **Behavior**: The solution curves appear periodic and oscillate around the equilibrium point.

#### Graph: \( x(t) \) with \( x(0) = -2 \), \( x'(0) = 2 \)
- **Description**: This plot illustrates the solution \( x(t) \) for the initial conditions \( x(0) = -2 \), \( x'(0) = 2 \).
- **Behavior**: The solution shows a similar oscillatory behavior with apparent periodicity but with potentially different amplitude and period.

#### Detailed Analysis
- **Top Left Graph**: Plot for \( x(0) = 1 \), \( x'(0) = 1 \). The curve oscillates with notable periodicity and a maximum amplitude of approximately 4.
