If one of the lines of `my^(2)+(1-m^(2))xy-mx^(2)=0` is a bisector of the angle between the lines `xy=0`, then m is

The angle between the lines xy=0 is

If one of the lines of m y^2+""(1-m^2)x y-m x^2=""0 is a bisector of the angle between the lines x y""=""0 , then m is (1) -1//2 (2) -2 (3) 1 (4) 2

If one of the lines of my^2+(1-m^2)xy-mx^2=0 is a bisector of the angle between lines xy=0 , then cos ^(-1) (m) is

If one of the lines represented by the equation lambda y^(2)+(1-lambda^(2))xy-lambdax^(2)=0 is bisector of the angle between the lines xy=0 , then, lambda=

Angle between the pair of lines xy=0 is

The angle between the lines x^(2)+4xy+y^(2)=0 is

The angle between the lines ay^(2)-(1+lambda^(2)))xy-ax^(2)=0 is same as the angle between the line:

If one of the lines given by kx^(2)+xy-y^(2)=0 bisects the angle between the co-ordinate axes, then k=
