If the line ax+by+c=0 is a normal to the curve xy=1 then

If the line ax + by + c = 0 is a normal to the curve xy = 1 then

If the line ax+by+c=0 is a normal to the curve xy=1 , then :

If the line ax+by+c=0 is a normal to the curve xy=1 at the point (1,1), then prove that a and b are of opposite signs.

If the line ax+by +c =0 is a normal to the curve xy=1 at the point (1, 1), then -
