In a triangle ABC, 2ac sin`((A-B+C)/2)` =

In a triangle ABC, 2 ac sin (1/2(A-B + C)) =

In a triangle ABC,2ac sin((1)/(2))(A-B+C)=

A, B and C are interior angles of a triangle ABC, then sin ((B + C)/(2)) =

In a Delta ABC,2ac sin((A-B+C)/(2)) is equal to (a)a^(2)+b^(2)-c^(2)(b)c^(2)+a^(2)-b^(2)(c)b^(2)-c^(2)-a^(2)(d)c^(2)-a^(2)-b^(2)

In a triangle ABC, prove that :a sin((A)/(2)+B)=(b+c)sin((A)/(2))

In a triangle ABC sin (A/2) sin (B/2) sin (C/2) = 1/8 prove that the triangle is equilateral

In any triangle ABC, show that: 2a sin((B)/(2))sin((C)/(2))=(b+c-a)sin((A)/(2))
