In `/_\ ABC,` if `2b=a+c` then `cot(A/2)cot(C/2)=`

In /_ABC, if 3a=b+c, then cot((B)/(2))cot((C)/(2))=

In a !ABC , if 3a = b + c , then cot B/2 cot C/2 =

If, in Delta ABC, 3a = b + c then: cot (B/2) cdot cot (C/2) = .....

If in a triangle ABC ,b +c=4a then cot(B/2)cot(C/2) is equal to

In /_ABC if cot((A)/(2)):cot((B)/(2)):cot((C)/(2))=3:5:7 then a:b:c?

In a /_ABC, if b^(2)+c^(2)=3a^(2), then cot B+cot C-cot A is equal to

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

In any Delta ABC, prove that cot((A)/(2))+cot((B)/(2))+cot((C)/(2))=(a+b+c)/(b+c-a)cot((A)/(2))

In Delta ABC, prove that: (cot((A)/(2))+cot((B)/(2)))(a sin^(2)((B)/(2))+b sin^(2)((A)/(2)))=c cot((C)/(2))
