The Answer of Let $\vec { F } = \left( 9 x ^ { 2 } + 6 y \cos ( x y ) \right) \vec { i } + ( 2 y + 6 x \cos ( x y ) ) \vec { j }$ .
Calculate $\int_{C} \overline{\vec{F}} \cdot \overline{d r}$ where C is the curve shown below.

Let F⃗=(9x2+6ycos⁡(xy))i⃗+(2y+6xcos⁡(xy))j⃗\vec { F } = \left( 9 x ^ { 2 } + 6 y \cos ( x y ) \right) \vec { i } + ( 2 y + 6 x \cos ( x y ) ) \vec { j }F=(9x2+6ycos(xy))i+(2y+6xcos(xy))j​

Let $\vec { F } = \left( 9 x ^ { 2 } + 6 y \cos ( x y ) \right) \vec { i } + ( 2 y + 6 x \cos ( x y ) ) \vec { j }$
