8. (8 points) Find the function f if ∇f=⟨3x2y+y2,x3+2xy⟩, and evaluate the integral ∫C∇f⋅dr with and without the Fundamental Theorem of Line Integral, where C is the curve r(t)=⟨2t,5t⟩,0≤t≤1. 9. (8 points) Let F be the vector field defined by F(x,y)=⟨3x+5y,−x2+7y⟩. Evaluate the following line integral with and without Groen's 'Theorem. ∫Cp⋅dr, where C is the positively oriented triangle bounded by the axes and the line x+y=3.
