I need help with #1

Transcribed Image Text:**Problem 1:**
Evaluate the line integral \(\oint_C 3y^2 \, dx + 2xy \, dy\) using two different methods.
**Details:**
- \(C\) is the boundary of the graphs:
- \(y = x^2\) from \((3, 9)\) to \((0, 0)\)
- Followed by the line segment from \((0, 0)\) to \((3, 9)\).
This problem involves calculating the line integral of a vector field around a closed curve \(C\), using two different approaches. The path \(C\) is defined in two parts, first along the parabola \(y = x^2\) and then along a straight line.
