1. The problem statement, all variables and given/known data Evaluate the line integral over the curve http://webwork.math.ttu.edu/webwork2_files/tmp/equations/33/92ca0e3b907f876e5a974ad1457d1f1.png [Broken] from to http://webwork.math.ttu.edu/webwork2_files/tmp/equations/6f/bccf9dd59b9c22450c590a042bb77d1.png [Broken]. ∫-ydx+3xdy (over the curve C) 2. Relevant equations 3. The attempt at a solution I'm really stuck on this problem not doing very well with line integrals. I started by changing y^2=x to parametric --> x=t^4 y=t^2 Then I took the derivate of each one --> dx=4t^3dt dy=2tdt I then plugged in each term into the given integral --> ∫-ydx+3xdy (over the curve C) = ∫-(t^2)(4t^3)+3(t^4)(2t)dt Would I use the points given to get my limits of integration or am I way off?
