Are we allowed to quote the equation of a tangent/normal/chord of contact etc. in conics questions? Or do we have to derive them?

Ah ic.Captain pi said:You must ALWAYS derive equations unless the equation is given in the question or was found in a subquestion of the same Question in each exam.
There has never been such a question given in the HSC.jumb said:Look at the marks. If It's a 1 mark question, quote the formula.
