**Problem:**

5. Shade in the area given by the integral 

\[
\int_{1}^{2} y^2 \, dy.
\]

**Graph/Diagram Explanation:**

The diagram features a coordinate plane with axes labeled \( x \) and \( y \). The horizontal axis represents \( x \) and the vertical axis represents \( y \). The graph displays the curve of the function \( y = \sqrt{x} \), a standard square root function.

- **Axes and Origin:**
  - The \( x \)-axis (horizontal) and \( y \)-axis (vertical) intersect at the origin \((0, 0)\).
 
- **Grid:**
  - The background contains a grid composed of squares, providing reference points for plotting and reading coordinates.

- **Function \( y = \sqrt{x} \):**
  - The graph shows this function beginning near the origin and increasing gradually. This curve represents the relationship where \( y \) is the square root of \( x \).

The task is to compute and shade the region corresponding to the definite integral \(\int_{1}^{2} y^2 \, dy\). This integral involves calculating the area between \( y = 1 \) and \( y = 2 \) on the \( y \)-axis, and \( y^2 \) as the function of \( y \).

**Note for Students:**

- The integral provided represents the area under the curve \( y^2 \) from \( y = 1 \) to \( y = 2 \), in the \( y \)-coordinate system, not along the path of \( y = \sqrt{x} \).
- Focus on understanding the transition between variables used in defining functions and calculating the area under those functions.
