If `theta` is the angle between the lines represented by `ax^(2)+2hxy+by^(2)=0`, then `tantheta=`

If theta is the angle between the lines represented by ax^(2)+2hxy+by^(2)=0 then show that Cos theta=(|a+b|)/(sqrt((a-b)^(2)+4h^(2)))

If theta is the acute angle between the lines represented by kx^(2)-4xy+y^(2)=0 and tantheta=(1)/(2) , then k=

If theta is the angle between the pair of lines represented by ax^2 + 2hxy + by^2 = 0 , then prove that cos theta= (|a+b|)/(sqrt((a-b)^2 + 4h^2))

If theta is the acute angle between the lines given by ax^(2) + 2hxy + by^(2) = 0 then prove that tan theta = |(2 sqrt (h^(2) - ab))/(a + b)| . Hence find acute angle between the lines 2x^(2) + 7xy + 3y^(2) = 0

if h^2=ab , then the lines represented by ax^2+2hxy+by^2=0 are

if h^2=ab , then the lines represented by ax^2+2hxy+by^2=0 are

if h^2=ab , then the lines represented by ax^2+2hxy+by^2=0 are

if h^2=ab , then the lines represented by ax^2+2hxy+by^2=0 are
