# Find Work Done by $$\vec F$$?

If a force acting on a particle can be described by the equation $$\vec F = \left(\dfrac{\sin y}x\right) \vec i + \left( \ln x \cos y\right) \vec j$$, then find the work done by $$\vec F$$ in moving an object from $$\left( e, \dfrac{\pi }4 \right)$$ to $$\left( e^7, \dfrac{3\pi}4 \right)$$.
