Find the coordinates of the points on the curve y = x^2/(2x-1) where dy/dx = 0.
~~~~~~~~~~~~~~~~~~


            In this problem, there are TWO points, satisfying the condition dy/dx=0.

            @josgarithmetic found one point and missed another.

            I came to bring full correct solution.


 = ((2x-1)(x^2)'-x^2(2x-1)')/(2x-1)^2


 = 


 = 


 = 


 = 0   has two solutions  x= 0  and  x= 1.


The two points on the curve with zero derivative are  (x,y) = (0,0)  and  (x,y) = (1,1).      ANSWER

    Plot  y =   (red)  and  y= 1  (horizontal tangent, green)


Solved (correctly).
