Geometry: I don't know the relationship between the tangents and secantes.

Thanks Geno, I always forget that one. :)

 

Geno,

I was looking at this one from yesterday, maybe from the same guest, i haven't worked it out yet.

Maybe you would like to take a look.  :)

Guest,

It would be much easier to find and track you questions (for you and everyone else) if you became a member! 

You would even get email alerts (if you ask for them) when someone answers you!
