Consider the parabola ` sqrtx+sqrty= sqrt a ` the axis of the parabola is

sqrtx sqrty =sqrtxy is true only when

Consider the parabola x^(2) +4y = 0 . Let P(a,b) be any fixed point inside the parabola and let S be the focus of the parabola. Then the minimum value at SQ +PQ as point Q moves on the parabola is (a) |1 -a| (b) |ab|+1 (c) sqrt(a^(2)+b^(2)) (d) 1-b

AP is perpendicular to PB, where A is the vertex of the parabola y^(2)=4x and P is on the parabola.B is on the axis of the parabola. Then find the locus of the centroid of o+PAB .

Consider the parabola y=x^2 The shaded area is

2/sqrtx + 3/sqrty = 2
