If ax^(2)+2hxy+by^(2)=1, then (d^(2)y)/(dx^(2)) is (a) (h^(2)-ab)/((hx+by)^(2))( b) (ab-h^(2))/((hx+by)^(2))(h^(2)+ab)/((hx+by)^(2)) (d) none of these

IF ax^2+2hxy+by^2=1 , show that, (d^2y)/(dx^2)=(h^2-ab)/((hx+by)^3) .

If ax^(2)+2hxy+by^(2)=c^(2), verify that (dy)/(dx)*(dx)/(dy)=1

If ax ^(2) + 2 hxy + by ^(2) =0 then (dy )/(dx) =

If y^2 = ax^2 + b , prove that (d^2y)/(dx^2) = ab/y^3
