Below, 'S' represents the integral sign.
1) S_c xy dx + y^5 dy
C is the triangle with verticies (0,0), (2,0) and (2,1).
2) S_c (y + e^sqrt(x) )dx + (2x + cos(y^2) ) dy
C is bounded by the region enclosed by parabolas y = x^2 and x = y2
3) S_c x^2y dx - 3y^2 dy
C is the circle x^2 + y^2 + 1
4) S_c (x^3 - y^3) dx + (x^3 + y^3) dy
C is the boundary of the region between circles x^2 + y^2 = 1 and x^2 + y^2 = 9.© BrainMass Inc. brainmass.com June 3, 2020, 9:19 pm ad1c9bdddf
