Find the equations of the tangents to the ellipse
which are perpendicular t0 the line
I am not sure how to work out the equations of the tangents, when I have not been given a specified point,
And if the tangents are perpendicular to the line, than it has to have a gradient of
that's all I am able to do, any help appreciated.
