I.4.41 Curvilinear Integrals

Condition: Calculate the curved integral \ (\ oint_ {l} p d x+q d y \) along the closed contour \ (l \) in a positive direction using the Green formula. \ (P = \ sqrt {x^{2}+y^{2}} - 7 y, q = y \ ln \ left (x+\ sqrt {x^{2}+y^{2}} \ right): \) \ (l \) - the circle of radius 1 with the center at the point at the point at the point at the point at the point of \ ((1,1) \).
