If the equation of the The Pair of Straight Lines passing through (1, 1), one making an angle θ with the positive direction of x-axis and the other making the same angle with the positive direction of y-axis is , then sin 2θ =
The joint equation of the given lines is
Shifting origin at (1, 1) it reduces to
. Lines represented by this equation make angle with x-axis.
The value of λ for which the lines joining the point of intersection of curves C1 and C2 to the origin are equally inclined to the axis of X.
If one of the lines given by the equation coincide with one of those given by and the other lines represented by them be perpendicular, then
If the pair of lines have exactly one line in common, then a =
If one of the given by , then cequals
Area of the triangle formed by the line x + y = 3 and angle bisectors of the pair of the straight lines is
If the The Pair of Straight Lines given by forms an equilateral triangle with the line ax + by + c = 0, then (A + 3B)(3A + B) =
The area (in square units) of the quadrilateral formed by two pair of the lines
The equation represets
If the pair of lines lie along diameters of a circle and divide the circle into four sectors such that the area of one of the sectors is thrice the area of the another sector, then
If θ1 and θ2 be the angle which the lines given by
make with the axis of x, then for
