Best ResponseYou've already chosen the best response.0(2/3) * x^(1/3) + (2/3) * y^(1/3) * (dy/dx) = 0 dy/dx = x^(1/3) / y^(1/3)

Best ResponseYou've already chosen the best response.0i filled in both x and y. and got a number. i used that as my slope in the equation yy1=m(xx1)

Best ResponseYou've already chosen the best response.0dy/dx = x^(1/3) / y^(1/3) i replaced x and y with given points in this, and got 1.732

Best ResponseYou've already chosen the best response.0dy/dx = (3sqrt(3))^(1/3) i get 0.577

Best ResponseYou've already chosen the best response.0y =1 0.577(x+3sqrt(3)) y= 1 0.577x 3 y = 0.577x 2

Best ResponseYou've already chosen the best response.0in fact dy/dx = 1/sqrt(3) so : y = x/sqrt(3) 2
