### Problem Statement
**Solve the equation**
\[ 2y y'' = 1 + (y')^2 \]
### Equation Breakdown
- **\( y \)**: A function of a variable, typically denoted as time or space.
- **\( y' \)**: The first derivative of \( y \), representing the rate of change of \( y \).
- **\( y'' \)**: The second derivative of \( y \), representing the acceleration or the curvature of \( y \).
- **Equation**: This is an example of a second-order differential equation, which relates a function with its derivatives.
### Step-by-Step Guide
1. **Identifying the Type of Equation**:
- The equation presented is a second-order, non-linear differential equation due to the presence of both \( y'' \) and \((y')^2\).
2. **Approach to Solve the Equation**:
- Methods such as substitution, integration, or using special functions might be applicable depending on boundary conditions or simplifications.
3. **Potential Methods**:
- **Reduction of Order**: Convert it to a first-order system or simplify using substitutions.
- **Numerical Solutions**: Apply numerical methods if an analytic solution is not feasible.

### Graphical Representation
- There is no graph or diagram provided with the equation.
- Visualization may be achieved by plotting potential solutions after deriving or approximating them.
