Determine the minimum value of a positive integer N, satisfying:
cos 96o + sin 96o
tan 19No = -----------------
cos 96o - sin 96o

I did the same , but copied the wrong coefficient (17 instead of 159):
LS= -0.809784 approx.
arctan(19N)= arctan( -0.809784 )=-31o +N*180o
This angle should be divisible by 19
for k=17 it is 3021
LS=RS= -0.809784 approx.
so the answer is N = 3021/19= 159
I was exhausted when I have typed in my answer,- since I HAVE SPENT A LOT OF TIME trying to solve it analytically.
