The area of the triangle formed by the co-ordinate axes and a tangent to the curve $x y=\mathrm{a}^2$ at the point $\left(x_1, y_1\right)$ is _______ sq. units (where a, $x_1$ and $y_1$ are non-zero)

The minimum value of the slope of the tangent to curve $y=x^3-3 x^2+2 x+93$ is

The approximate value of $\frac{1}{(2.002)^2}$ is
