Area of Bounded Regions
A tangent to the curve, $$y=f(x)$$ at $$P(x, y)$$ meets $$x-$$axis at $$A$$ and $$y-$$axis at $$B$$. If $$AP:BP=1:3$$ and $$f(1)=1$$, then the curve also passes through the point.
A helicopter is flying along the curve given by $$y - x^{3/2} =7, (x \ge 0)$$. A solider positioned at the point $$\left(\dfrac{1}{2}, 7\right)$$ wants to shoot down the helicopter when it is nearest to him. Then this nearest distance is:

Let $$y = f(x)$$ be a parabola, having its axis parallel to y-axis, which is touched by the line $$y =x$$ at $$x = 1$$, then
