How do I find the normal and tangent equations?
x^2/4 + (y+2)^2 = 1 (ellipse)
"Find the parametrized equation to the tangent and normal in point (-2, -2)."
I believe the tangent is [-2, -2] + t[0, -1] (although I am not sure),
and I believe the normal is [-2, -2] + t[-1, 0] (How do you get to the solution? I just "saw" it, but I cant figure out how to mathematically do it!)
Tried N = N(vector) / N(scalar), but .. nope
