The abcissa of the points of the curve y = x(x - 2)(x - 4) where tangents are parallel to x-axis is obtained as
AOB is the positive quadrant of the ellipse x2 ∕ a2 + y2 ∕ b2 = 1, where OA = a, OB = b. The area between the arc AB and the chord AB of the ellipse is

The general solution of the differential equation is given by
If y=x2(x-2)2, then the values of x for which y is increasing, are
If S is the set of all real x such that 2x - 1/2x3 + 3x2 + x is positive, then S contains
Out of 15 points in a plane, no three are in a straight line except 8 points which are collinear. How many triangles can be formed by joining them?
Let A and B be two events such that P(A) = 0.3, P(A∪B) = 0.8, if A and B are independent events, then P(B) is equal to
