hey guys..fr this n the questions tht follow pls giv ur line of thought or concept u used also apart frm the answer..
the family of curve passing through the point ( (root) c, 0) and whose tangent form an angle pi/4 with the curve xy=c, is:
(a) 2y + (2 + 
) 
c = 2x + 4 c cos-1( 2x/3 c ) (b) 2y + (2 - ) c = 2x + 4 c tan-1( x/ c ) (c) 2y + (2 - ) c = 2x - 4 c tan-1( x/ c ) (d) none of these..
