Line Integrals

  1. Dec 5, 2007 #1
    1. The problem statement, all variables and given/known data
    Integrate h(x,y)=yi - xj over the triangle with vertices (-2,0), (2,0), (0,2) tranversed counterclockwise

    2. Relevant equations

    3. The attempt at a solution
    integral y-x
    integral (0)-(-2+4t)*4 from 0 to 1 = 0
    integral (2t)*2-(2-2t)*-2 from 0 to 1 = 4
    integral (2-2t)*-2-(-2t)*-2 from 0 to 1 = -4

    I dont get the right answer, the correct answer is -8
