If cot^(-1)((n)/(pi))>(pi)/(6),n in N, then the maximum value of n is :

If cot^(-1)(n)/(pi)>(pi)/(6),n in N, then the maximum value of n is 6(b)7 (c) 5 (d) none of these

Q.if cot ^(-1)((n)/(pi))>(pi)/(6),n in N, then the maximum value of 'n' is

If tan^(-)(x/(pi))lt (pi)/(3) ,x in N then the maximum vlaue of x is

If cos^(-1)((n)/(2pi)) gt(2pi)/(3) then maximum and minimum values of integer n are respectively

If sum_(n=0)^(oo)2cot^(-1)((n^(2)+n+4)/(2))=k pi then find the value of k

If lim_(n rarr oo)(prod_(r=1)^(n)sin((r pi)/(4n))cos((r pi)/(4n)))^((1)/(n))=(a)/(b) a,b in N then find the least value of (a+b)
