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(B/2)`

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)

If ABC is a triangle and tan"" (A)/(2) , tan"" (B)/(2) , tan "" (C )/( 2) are in H.P. then the minimum value of cot"" (B)/(2) is equal to

In triangle ABC , "tan"(A)/(2),"tan"(B)/(2),"tan"(C)/(2) are in H.P ., then the value of "cot"(A)/(2)xx"cot"(C)/(2) is equal to

If tan(A/2),tan(B/2),tan(C/2) are in H.P , where A,B,C are angles of a triangle, then the minimum value of cot^(2)(B/2) is

In Delta ABC, if tan""A/2,tan""B/2, tan""C/2 are in H.P, then a,b,c are in

In a Delta ABC tan ""A/2, tan ""B/2, tan ""C/2 are in H.P., then the vlaue iof cot ""A/2 cot ""C/2 is :

In a Delta ABC tan ""A/2, tan ""B/2, tan ""C/2 are in H.P., then the vlaue iof cot ""A/2 cot ""C/2 is :

In a triangle ABC,tan((A)/(2)),tan((B)/(2)),tan((C)/(2)) are in H.P.and the sides 'a' tan((C)/(2)) are and 'c' are given by 5and 9units,then the side 'b' is

* In a Delta ABC,If tan((A)/(2)),tan((B)/(2)),tan((C)/(2)) are in H.P.then a,b,c are in ,tan((C)/(2))
