are the curves x=y,x=-y????

prakhar February 21, 2011 at 5:25 pm

is answer is this? …… y^2 – x^2 + 2*x*y=0

x=y

Two curves dy/dx=y-x/x+y

or dy/dx=2×2+2y2

6. guys let us see it in this way::-

in the line x=y …. the tangent will be the line itself… thus the distance will be the distance of the point… and then the normal at the point will also be perpendicular to the line joining the point and origin… so both the distances are equal… the wat is the problem with x=y or x=-y???
