Find the equations of the tangent and normal to the hyperbola
at the point (x0, y0).
It is given that the equations of the tangent and normal to the hyperbola
, then,
On differentiating it with respect to x, we get,
![]()
![]()
![]()
Therefore, the slope of the tangent at (x0, y0) is

Then, the equation of the tangent at (x0, y0) is given by:
y - y0 =![]()
![]()
![]()

![]()
![]()
Then, slope of normal at (x0, y0)
=![]()
Therefore, the equation of the normal at (x0, y0) is
y - y0 =
(x - x0)
![]()
![]()
Therefore, the equation of the normal at (x0, y0) is
.
