If the chord y = mx + 1 of the circle x2 + y2 = 1 subtends an angle of 45oat the major segment of the circle, then m =
Since chord AB subtends 45o at P. Therefore, it makes 90o at the centreO.
The combine equation of OA and OB is
Lines given by this equation are at right angle.
The line y = mx bisects the angle between the lines
If two pairs of straight lines having equations have one line common then a =
The point of intersection of the The Pair of Straight Lines given by
The square of the distance between the origin and the point of intersection of the lines given by
The centroid of the triangle whose three sides are given by the combined equation
If first degree terms and constant term are to be removed from the equation , then the origin must be shifted at the point
The angle between the straight lines joining the origin to the points of intersection of and 3x – 2y = 1 is
All chords of the curve which subtend a right angle at the origin always pass through the point
If the pair of lines represented by intersect on y-axis, then
The straight lines represented by
