Use the surface integral in Stokes' Theorem to calculate the circulation of the field F around the curve C in the indicated direction. F = yi + xzj + x2k C: The boundary of the triangle cut from the plane 8x + y + z =8 by the first octant, counterclockwise when viewed from above. The circulation is (Type an integer or a fraction.)Use the surface integral in Stokes' Theorem to calculate the circulation of the field F = (y + z ) i+ (x2 + y)j+ (x+ y ) k around the curve C: The square bounded by the lines x = +3 and y = #3 in the xy-plane, counterclockwise when viewed from above.
