If A+B+C=pi and sin(A+(C)/(2))=k sin((C)/(2)), then tan((A)/(2))*tan((B)/(2)) is equal to

If A+B+C=pi and sin(A+(C)/(2))=k sin((C)/(2)) then (tan A)/(2)(tan B)/(2) is

If A + B + C = pi and sin(A +C/2)= ksin(C/2) , then tan(A/2).tan(B/2) is equal to

If A+B+C=pi and sin(A+(C)/(2))=n sin((C)/(2)), show that tan((A)/(2))*tan((B)/(2))=(n-1)/(n+1)

If A+B+C=pi , then tan((A)/(2))tan((B)/(2))+tan((B)/(2))tan((C)/(2))+tan((C)/(2))tan((A)/(2)) is equal to a) (pi)/(6) b)3 c)2 d)1

If A+B+C=pi, show that : tan.(A)/(2)tan.(B)/(2)+tan.(B)/(2)tan.(C)/(2)+tan.(C)/(2)tan.(A)/(2)=1 Hence deduce that : cot.(A)/(2)+cot.(B)/(2)+.cot.(C)/(2)=cot.(A)/(2).cot.(B)/(2)tan.(C)/(2) .
