I think someone posted a similar question but I wanted to clarify:
'If![](https://latex.codecogs.com/png.latex?\bg_white \theta +\epsilon = \frac{\pi}{2}...$ Show that the equation of the chord PQ has equation $ ay=b(\cos\theta+\sin\theta)x-ab $ Where $P(a\sec\theta,b\tan\theta), Q(a\sec\epsilon, b\tan\epsilon))
I have subbed in P, and shown that the LHS=RHS, and then for Q also, LHS=RHS
I tried doing it from y-y1=(m)(x-x1) but it got way too messy. Is this a valid 'show' that the chord PQ has that equation - just subbing it in and then showing that both satisfy?
Thanks
