tan((A+B)/(2))="cot"(C)/(2)

In triangle ABC , prove that tan (B-C)/2 =[( b-c) /(b+c )] cot A/2 , tan (C-A)/2 = [(c-a)/(c+a)]cot B/2 , tan (A-B)/2 = [(a-b)/(a+b)]cot c/2

In any Delta ABC(i)tan((B-C)/(2))=((b-c)/(b+c))(cot A)/(2)(ii)tan((A-B)/(2))=((a-b)/(a+b))(cot C)/(2)(iii)tan((C-A)/(2))=((c-a)/(c+a))(cot B)/(2)

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