(a) that P is the midpoint of AB

(b) that the area of Triangle OAB is the same for all positions of P.

Find the the equations of the normals to the curve xy=4 which are parallel to the line

4x-y-2=0.

I got the equation of the of the tangent at P to be yt

^{2}- 4t -x = 0

Not sure how to do a and b I don't really have much information about AB other than it's points like on P basically.
