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

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

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 theta is the measure of the acute angle between the lines represented by equation ax^(2)+2hx+by^(2)=0 , then prove that tan theta =|(2sqrt(h^(2)-ab))/(a+b)| where a+b ne 0 and ne 0. Find the condition for coincident lines.

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 lines y = mx bisects the angle between the lines ax^(2) +2hxy +by^(2) = 0 if

If the acute angle between the lines ax^2+2hxy +by^2=0 is 60^@ then show that (a+3b)(3a+b)= 4h^2

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

If theta is the acute angle butween the pair of lines represented by 3x^(2)-8xy+4y^(2)=0 then (2cos theta+3sin theta)/(4sin theta+5cos theta) is
