Themofthe planecurvex4+y3x2y=0,x=tt3,y=t2 t4 was derived: A) Using Green's formula, show that the integral needed for the x-coordinate of the center of the closed loop D is given by the formula 1 2 a: GM 2 :17 dy. D 2 s B) Someone came up with a similar formula for the y-integral of the center. (There are an infinite number of options.) C) Calculate (x, y)
