If `A, B and C` are the angles of a triangle then `tan(B/4+C/4)` equals to

If A, B, C are the angles of a triangle then tan ((B+C)/2)=

If A,B and C are the angles of a plain triangle and tan(A/2)=1/3 , tan(B/2)=2/3 , then tan(C/2) is equal to

If A ,B, C are the angles of a triangle , then : tan""(A)/(2) * tan""(B+C)/(2) +cos""(A+B)/(2) *csc""(C)/(2)=

If A,B,C are the angles of a triangle, show that, (iv) (tan(B + C) + tan (C + A) + tan (A + B))/(tan (pi - A) + tan(2pi - B) + tan (3pi - C)) = 1

If A, B and C are angles of a triangle such than tan A = 1, tan B = 2, then what is the value of tan C ?

If A, B and C are angles of a triangle such that angleA is obtuse, then show tan B tan C lt 1.

Let A,B and C are the angles of a plain triangle and tan((A)/(2))=(1)/(3),tan((B)/(2))=(2)/(3) then tan((C)/(2)) is equal to
