by using the formula


tanA=modulas of (m1-m2)/(1+m1m2)


where A=45 and m1=+1


we can fine m2 from that we get two values


so we get two lines.


using the three lines we find the oint of intersections.


from the area formula we get the area covered by the triangle.

If the lines joining origin and point of intersection of curves ax 2 +2hxy+by 2 +2gx=0 and a1x 2 +2h1xy+b1y 2 +2g1x=0 are mutually perpendicular,then prove that- g(a1+b1)=g1(a+b)
 
 
a petty question on homogenization of equation. ax 2 +2hxy+by 2 +2gx(1)=0 ...1 a1x 2 +2h1xy+b1y 2 = -2g1x ...2 a1x 2 +2h1xy+b1y 2 /(-2g1x)=1 ...3 now replacing 1 in eq 1 by a1x 2 +2h1xy+b1y...
