Question about Conics (1 Viewer)

[Axio]

Hi,

I was just wondering in regards to conics questions in exams that require you to find the tangent/normal/chord of contact etc, do you need to prove them from scratch for any question or are there some questions where you can just write the formula down or whatever?

Thanks

Always prove them unless they give you the equations.
