`cot(A/2)+cot(B/2)+cot(C/2)=cot(A/2)cot(B/2)cot(C/2)`

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 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)=

If A+B+C=pi Prove that cot A/2+cot tB/2+cot C/2=cot A/2cot B/2cot C/2

if A+B+C=pi prove that cot((A)/(2))+cot((B)/(2))+cot((C)/(2))=cot((A)/(2))xx cot((B)/(2))xx cot((C)/(2))

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 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)=

If A+B+C=180^(@) , then the value of cot(A/2)+cot(B/2)+cot(C/2) will be .............. A) 2 cot ""A/2 cot ""B/2 cot""C/2 B) 4 cot ""A/2 cot ""B/2 cot ""C/2 C) cot ""A/2 cot ""B/2 cot ""C/2 D) 8 cot ""A/2 cot ""B/2 cot ""C/2

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