" In "Delta ABC," the value of "(cot(A)/(2)cot(B)/(2)-1)/(cot(A)/(2)cot(B)/(2))=

In DeltaABC , the value of ("cot"(A)/(2)"cot"(B)/(2)-1)/("cot"(A)/(2)"cot"(B)/(2))

In triangle ABC, the value of (cot""A/2cot ""B/2-1)/(cot ""A/2 cot ""B/2) is

In triangle ABC the value of ( cot A/2 cot ""B/2 -1)/( cot""A/2 cot""B/2) is

In triangle ABC the value of (cot frac (A)(2) cot frac (B)(2)-1) /(cot frac (A)(2) cot frac (B)(2)) is :

In a triangle ABC if cot((A)/(2))*cot((B)/(2))=c,cot((B)/(2))*cot((C)/(2))=a and cot((C)/(2))*cot((A)/(2))=b then (1)/(s-a)+(1)/(s-b)+(1)/(s-c)=

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

In a triangle ABC, if r^(2)cot((A)/(2))cot((B)/(2))cot((C)/(2))=

In Delta ABC, cot ""(A)/(2) +cot""(B)/(2) + cot""(C)/(2)=

Delta ABC;(b-c)cot((A)/(2))+(c-a)cot((B)/(2))+(a-b)cot((C)/(2))

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