Inconsiderable Integer Illation (Posted on 2014-11-16)

Determine the minimum value of a positive integer N, satisfying:

           cos 96^o + sin 96^o
tan 19N^o = -----------------
           cos 96^o - sin 96^o

Numerator of RHS

= V2* (sin 96*cos45 + cos96*sin 45)

= V2*sin(96+45)

Denominator of RHS

= V2* (cos96*cos45 - sin 96*sin 45)

= V2*cos(96+45)

.... do I need to go on?
