If `I_n=int_0^(pi/4) tan^nx` then `lim_(nrarroo)n(I_n+I_(n-2))` equals (A) `1/2` (B) `1` (C) `oo` (D) `0`

If I_(n)=int_(0)^(pi//4) tan^(n) x dx, lim_(n to oo) n(I_(n+1)+I_(n-1)) equals

l_(n)=int_(0)^(pi//4)tan^(n)xdx , then lim_(nto oo)n[l_(n)+l_(n-2)] equals

I_n=int_0^(pi//4) tan^n x dx, then lim_(ntooo) n [I_n + I_(n+2)] is equal to (i)1/2 (ii)1 (iii)infty (iv) 0

IF I_n=int_0^(pi//4) tan^n x dx then what is I_n+I_(n+2) equal to

If l_(n)=int_(0)^(pi//4) tan^(n)x dx, n in N "then" I_(n+2)+I_(n) equals

If I_(n)=int_(0)^(pi//4)tan^(n)x dx, then 7(I_(6)+I_(8))=

lim_(x rarr oo)(1)/(1+n sin^(2)nx)is equal to -1 (b) 0 (c) 1 (d) oo

If I_(n)=int_(0)^((pi)/(4))tan^(n)theta then I_(8)+I_(6) equals
