find the locus of the mid points of the chord of the hyperbola x 2 /a 2 -y 2 /b 2 =1 which subtend a right angle at the origin.
consider the mid to be a point P (X 0, Y 0 ) now use the formula S 1 =S 11 you will get the equation of chord with its mid point. then homogenise this equation with the equation of given...

The distance between the lines represented by the equation x 2 +2root2 xy+2y 2 +4x+4root2 y+1 is:
let then which yields hence the two lines are as follows these are parallel lines When the lines are given by ax+by+c 1 =0 ax+by+c 2 =0 the distance between them can be expressed as so in...
