" 8.If "b+c=3a," then prove that "cot(B)/(2)*cot(C)/(2)=2

In /_\ABC ,3a=b+c,prove that cot(B/2).cot(C/2)=2

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

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

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

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)

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)
