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

Angle between the lines 2x^(2)-3xy+y^(2)=0 is

If the angle between the lines ax^(2)+xy+by^(2)=0 is 45^(@) , then

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

If the acute angle between the lines ax^(2)+2hxy+by^(2)=0 is congruent to the acute angle between the lines 3x^(2)-7xy+4y^(2)=0 , then

The joint equation of lines which bisect the angle between the two lines x^(2)+3xy+2y^(2)=0 is

If theta is the measure of acute angle between the pair of line repseented by ax^(2) + 2hxy + by^(2) = 0 , then prove that tan theta = |(2sqrt(h^(2) - ab))/(a+b)|,a + b ne 0 Hence find the acture angle between the lines x^(2) - 4xy + y^(2) = 0

The angle between the lines xy=0 is

If the lines x^(2)+2hxy-y^(2)=0 bisect the angle between the lines 2x^(2)+10xy-y^(2)=0 then h=

If theta is the angle between the lines ax^(2)+2hxy+by^(2)=0, then angle between x^(2)+2xy sec theta+y^(2)=0 is
