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 a DeltaABC , 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) equals

In any triangle ABC prove that cot(A/2)+cot(B/2)+cot(C/2)=cot(A/2)cot(B/2)cot(C/2)

In any triangle ABC prove that cot(A/2)+cot(B/2)+cot(C/2)=cot(A/2)cot(B/2)cot(C/2)

In a triangle ABC,if a cot A+b cot B+c cot C=

In any triangle prove that cot(A/2)+cot (B/2)+cot(C/2)=cot(A/2)cot(B/2)cot(C/2)

If A+B+C= pi ,prove that cot(A/2)+cot(B/2)+cot(C/2)=cot(A/2)cot(B/2)cot(C/2)

If in a triangle ABC cot(A/2)+cot(C/2)=2cot(B/2) then find the minimum value of cot(B/2)

If A+B+C=pi , prove that : cot( A/2)+ cot(B/2) + cot( C/2) = cot( A/2) cot(B/2) cot(C/2)

If A+B+C=pi , prove that : cot (A/2)+ cot(B/2) + cot(C/2) = cot(A/2) cot (B/2) cot (C/2)
