In a triangle `ABC` if `b+c=3a` then find the value of `cot(B/2)cot(C/2)`

In a triangle ABC, if 3a = b+c, then the value of cot ""(B)/(2) cot ""C/2 is-

In a triangle ABC if a^(2)+b^(2)=101c^(2) then find the value of (cot C)/(cot A+cot B)

In a triangle ABC,a-2b+c=0. The value of cot((A)/(2))cot((C)/(2)) is

If three sides a,b,c of a triangle ABC are in arithmetic progression, then the value of cot(A/2), cot(B/2), cot(C/2) are in

if ABC is a triangle and tan(A/2), tan(B/2), tan(C/2) are in H.P. Then find the minimum value of cot(A/2)*cot(C/2)
