Homework Statement
Given a vector field
[itex] F(x,y,z) = (yz + 3x^{2})\hat{i} + xz\hat{j} + xy\hat{k}[/itex]
Calculate the line integral
[itex]∫_{A}^{B}F\bullet dl[/itex]
where A = (0,1,3) and B = (1,2,2)
Homework Equations
Right, first of all, what is dl ? I've gone over all my course notes and don't see dl anywhere. I managed to find on this site that dl = (dx, dy, dz). Is that the case?
If so, my attempt at the solution is
[itex]∫_{A}^{B}(yz + 3x^{2})dx + xzdy + xydz[/itex]
Now what? I'm not really sure how to set the intervals from those 2 points in space. Am I supposed to do something like
[itex]∫_{0}^{1}(yz + 3x^{2})dx + ∫_{1}^{2}xzdx +∫_{3}^{2}xydz[/itex] ?
Thanks for any assistance.
