Given circle is x2 +y2 =16 and tangents are drawn from P (0,h) such that they intersect x-axis at A and B. Area of ?AP B is minimum, only when it is a right angled triangle with right angle at P. ? Equations of AP and BP are x+y ?h= 0 and x?y+h =0 respectively. As AP is tangent to the circle distance from origin to x +y ?h= 0 is equal to radius.
