Three points $O(0,0)$, $P(a,a^2)$, $Q(-b,b^2)$, $a>0$, $b>0$, are on the parabola $y=x^2$. Let $S_1$ be the area of the region bounded by the line PQ and the parabola, and $S_2$ be the area of the triangle $OPQ$. If the minimum value of $\frac{S_1}{S_2}$ is $\frac{m}{n}$, $\gcd(m,n)=1$, then $m+n$ is equal to:
Let O(0,0), A(2,0) and B\(\left(1, \dfrac{1}{\sqrt{3}}\right)\) be the vertices of a triangle. Let R be the region consisting of all those points P inside \(\triangle OAB\) which satisfy \(d(P, OA) \leq \min\{d(P, OB), d(P, AB)\}\) where \(d\) denotes the distance from the point to the corresponding line. Sketch the region R and find its area.
