Plot Sin Cos
1. **Problem Statement:** Plot the functions $y_1(x) = \sin(x)$ and $y_2(x) = \cos(x)$ on the same graph for $x$ ranging from $-2\pi$ to $2\pi$ with increments of $0.1$.
2. **Setting up MATLAB Plot:**
- Define the domain: $x = -2\pi : 0.1 : 2\pi$
- Compute function values: $y_1 = \sin(x)$ and $y_2 = \cos(x)$.
3. **Plotting Curves:**
- Plot $y_1$ with a dashed line style.
- Plot $y_2$ with a continuous line style.
4. **Graph Customization:**
- Label x-axis as "x-axis".
- Label y-axis as "y-axis".
- Set title to "Plot of sin(x) and cos(x)".
- Add legend showing $y_1(x) = \sin(x)$ and $y_2(x) = \cos(x)$.
- Set x-axis limits to $[-2\pi, 2\pi]$.
- Set y-axis limits to $[-3, 3]$.
5. **Explanation:**
- Sine and cosine functions oscillate between -1 and 1.
- Despite their natural range, we expand y-axis limits to $[-3,3]$ as specified.
- The dashed line differentiates $y_1$ from the continuous line of $y_2$.
- Legend and axis labels help interpret the graph clearly.
