Sin A Cos C + Cos A Sin C

In Delta ABC, cscA (sin B cos C + cos B sin C) =

If A+B+C=180^(@) then the value of cosec A(sin B cos C+cos B sin C) is

In a ABC, right angled at A, if tan C=sqrt(3) , find the value of sin B cos C+cos B sin C

Prove that sin(A+B+C)=sin A cos B cos C+cos A sin B cos C+cos A cos B sin C-sin A sin B sin Ccos(A+B+C)=cos A cos B cos C-cos A sin B sin C-sin A cos B sin C-sin A sin B cos C

If A+B+C=pi , prove that sin 2A+sin 2B-sin 2C=4 cos A cos B sin C

Sin C± Sin D || Cos C ± Cos D

a cos A + b cos B + c cos C = 2a sin B sin C
