How to use green's theorem when the C is oriented clockwise

Green's Theorem is a mathematical tool used to calculate the circulation of a vector field along a closed curve, also known as a line integral. To use Green's Theorem for a clockwise-oriented curve, the direction of the curve must be reversed and the signs of the partial derivatives must also be reversed in the formula.
The formula for Green's Theorem for clockwise-oriented C is ∯_{C}Pdx + Qdy = -∯_{D}Qdx - Pdy, where P and Q are the components of the vector field and the curves C and D enclose a region in the counterclockwise and clockwise directions, respectively.
Using Green's Theorem for clockwise-oriented C allows us to calculate the line integral of a vector field along a closed curve in the opposite direction, which can be useful in certain applications where the direction of the curve is known to be clockwise.
Yes, Green's Theorem can be used for any closed curve, whether it is clockwise or counterclockwise. However, the formula and direction of the integral will vary depending on the orientation of the curve.
Green's Theorem is a special case of Stokes' Theorem, which is a more general theorem that relates the circulation of a vector field along a closed curve to the flux of the curl of the vector field through a surface bounded by the curve. In other words, Green's Theorem is a simplified version of Stokes' Theorem for two-dimensional vector fields.
