Let the tangents drawn to the circle x2+y2=16 from the point P(0,h) meet the x-axis at point A and B.
Let the tangents drawn to the circle x2+y2=16 from the point P(0,h) meet the x-axis at point A and B. If the area of triangle APB is minimum, then h equals to?

While writing equation of tangent y=√(h^2-16)/4 x+h/4 instead of h/4 it should be h
Since h/4 has no impact on answer as it gets vanished further you may have not noticed the error
