" The value of "tan(n pi+(pi)/(3)),n in I" is "

If tan x=3cot x, then the general value of x is a.n pi+(pi)/(6),n in I b.n pi+(pi)/(3),n in I c.n pi+-(pi)/(6),n in I d.n pi+-(pi)/(3),n in I

If (1)/(6)sin theta,cos theta and tan theta are in GP,then the general value of theta is (i) 2n pi+-(pi)/(3)( ii) 2n pi+-(pi)/(6) (iii) 2n pi+-(-1)^(n)(pi)/(3)( iv )n pi+-(pi)/(3)

The value of sin pi/n + sin (3pi)/n+ sin (5pi)/n+... to n terms is equal to

The minimum value of n for which tan^(-1)'n/pi gt (pi)/(4), n in N , is valid is 5.

The minimum value of n for which tan^(-1)'n/pi gt (pi)/(4), n in N , is valid is 5.

If t a n x=3cot x , then the general value of x is (A) npi+pi/6,"n" in "I" (B) npi+pi/3,"n" in "I" (C) npi+-pi/6,"n" in "I" (D) npi+-pi/3,"n" in "I"

The value of (sin pi)/(n)+(sin(3 pi))/(n)+(sin(5 pi))/(n)+... to n terms is equal to

If 4cos^(2)theta+sqrt(3)=2(sqrt(3)+1)cos theta, then theta is 2n pi+-(pi)/(3),n in I(b)2n pi+-(pi)/(4),n in I2n pi+-(pi)/(6),n in I(d) none of these

If I_n = int_0^(pi//4) tan^n theta d theta , then for any +ve integer n, the value of n(I_(n - 1) + I_(n + 1)) is :

The value of lim_(n->oo) [tan(pi/(2n)) tan((2pi)/(2n))........tan((npi)/(2n))]^(1/n) is
