**Problem Statement:** 3. Let \( C \) be the part of the circle with radius 3 in the first quadrant as shown in the picture. **Diagram Explanation:** - The diagram depicts a quarter-circle in the first quadrant of a Cartesian coordinate system. - The center of the circle is at the origin (0,0). - The radius of the circle is 3. - The endpoints of the quarter-circle are at (3,0) on the x-axis and (0,3) on the y-axis. **Problem (a):** (a) Find a parametric equation \( \mathbf{r}(t) \) of \( C \). (Make sure to write the beginning and ending values of \( t \).)

Here's the transcription of the image, suitable for an educational website: --- **Problem Statement:** (b) Evaluate the line integral \[ \int_{C} x \, dy - y^2 \, dx \] **Explanation:** This mathematical expression is a line integral, used in calculus to integrate functions along a curve or path \(C\). The expression \(x \, dy - y^2 \, dx\) suggests a certain form of parametrization or explicit function representation is needed to evaluate it. Line integrals have important applications in various fields such as physics and engineering, particularly in calculating work done by a force field and fluid flow along a path.
