sin C - sin D =

If A+B +C=pi, then sin (A+B)= .............. A) sin A B) sin B C) sin A+sin C D) sin C

If : A+B+C=pi, "then" : sin 2A + sin 2 B - sin 2 C= A) 4 sin A * cos B * cos C B) 4 sin B * sin C * cos A C) 4 sin C * cos A * cos B D) 4 sin A * sin B * sin C

In a scalene triangle A B C ,D is a point on the side A B such that C D^2=A D *D B , sin A * sin B=sin^2(C/2) then prove that CD is internal bisector of /_C

Prove that: ("sin"(A-B))/(sin A sin B)+("sin"(B-C))/(sin B sin C)+("sin"(C-A))/(sin C sin A)=0

If p = sin (A-B) sin (C-D) q = sin (B-C) sin (A-D) , r = sin (C-A) sin (B- D) then
