Sum to Product Formula#!#Sin(C+D), Sin(C-D)...

Transformation sum into product || Product into sum(C,D Formulae)

Product C and D are respectively:

Statement:1 If cos(A+B)sin( C +D) = cos(A-B) sin(C-D) , then the values of cotAcotBcotC is cotD. And Statement:2: If cos(A+B) sin(C+D)= cos(A-B) sin(C-D) then the value of tanAtanBtanC is tanD.

Show that: sin(B-C)cos(A-D)+sin(C-A)cos(B-D)+sin(A-B)cos(C-D)

In equilibrium ABCD, prove thatL: i) sin(A+B)+sin(C+D)=0 ii) cos(A+D)-cos(B+C)=0

In a prisim mu=(sin[(A+D)//2])/(sin(A//2)) . Find the formula for the propagation of error in mu due to error in A and D.
