cot¯¹ n/Π>Π/6 n belongs to natural numbers, then the maximum value of n is (a) 1 (b) 5 (c) -5 (d) none of these

(b) 5
(c) -5
(d) none of these
From the graph ,we can see that cot x is periodic function with period as Π . hence ,cot¯¹ n/Π > Π/6 can be found only for ( 0 , Π ) n/Π > cot Π/6 n/Π > 31/2 n > Π.31/2 n > 5.43 or n>=6 answer: none of these -- regards Ramesh
