Points (1, 2) and (2, 1) are:

Let E be the ellipse x^(2)/9 + y^(2)/4 = 1 and C be the circle x^(2) + y^(2) = 9. Let P and Q be the points (1, 2) and (2, 1) respectively. Then,

Let E be the ellipse x^(2)//9+y^(2)//4=1 and C be the circle x^(2)+y^(2)=9 . Let P and Q be the points (1, 2) and (2, 1) respectively. Then
