Hi all,

Thanks for yesterday's points Chris.  I think either Happy7 or Rosala gave me 1 on my Lantern as well. Thanks Happy and Rosala  :)

 

Lots of great answers today from Mataxa, Rosala, Alan, CPhill, Geno3141, all-them-marvel-feels, Saseflower, Mekay14, pbclover and Heureka.  A big thank you to each of you :)

1) This trig one amused me - it will no doubt amuse me more when Geno explains himself.

2) this sum and product of the real roots of a polynomial created some interest. Thanks CPhill and Heureka

3) Heureka's answer to this co-ordinate geometry question looks interesting.  I answered it too.  We used very different techniques.  Thanks Heureka :)
