In Delta ABC, if tanA: tan B: tan C=1:2:3 , then sin A: sin B: sin C =

If,A,B,C are angles of a triangle and if none of them is equal to (pi)/(2) ,then tan A+tan B+tan C is cot A cotB cot C tan A tan B tan C sin A sin B sin C cos A cos B cos C

In /_ABC, if tan A:tan B:tan C=1:2:3, then sin A:sin B:sin C=?

If tan A =1/2, tan B=1/3, then cos 2A= ........... A) sin B B) sin 2B C) sin 3B D) -sin 2B

If tan A = (7)/(24) find the value of sin A cos A.

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 sin A : sin B : sin C = 3: 4: 5 then tan ""(A)/(2) : tan ""(B)/(2) : tan "" (C ) /(2) =

If cos A = tan B , cos B= tan C, cos C= tanA , show that sin A= sin B= sin C= 2 sin 18^(@)

In a Delta ABC if tan B=(2sin A sin C)/(sin(A+C)) then tan A,tan B,tan C are in
