cot b = 5/4
cot b = adj / opp
therefore, in triangle adj = 5, opp = 4
hyp = root ( 5^2 + 4^2)
hyp = root (25 + 16)
hyp = root 41
cosec b = hyp / opp
cosec b = root 41 / 4
sec b = hyp / adj
sec b = root 41 / 5
cosec ^2 b = (root 41 / 4) ^2
------> 41 / 16
sec ^2 b = (root 41 / 5)^2
--------> 41 / 25
