I am having some trouble with these 2 problems. Thank you so much for your help.

1) Evaluate the line integralCFdr where F = x + 3y, 2x and C is given byy=x2 from (0, 0) to (2, 4)

2) Let F =<2xy,x2+y> and C be defined by r(t) =<t+1,t2 for 1 t 2

a)Show that F is conservative

b) Find the potential function for F

c) EvaluateCFdr using the Fundamental Theorem of Line Integrals
