Determine the minimum value of a positive integer N, satisfying:
cos 96o + sin 96o
tan 19No = -----------------
cos 96o - sin 96o
(In reply to re(2): Actual answer -- calculator solution
Without analytical solution it boils down to check your level of working
with a standard scientific calculator.
I have expressed LS by a COS 96o but could neither find any reasonable connection with 19o nor did I got an irrational formula, like a+b*sqrt(c) that could be related to both angles.
I hope that KS either provides an "official" solution or declares that
he has none.
