(1) `SinACosC + CosASinC`

In a /_\A B C right angled at B , /_A=/_C . Find the values of (i) sinAcosC+cosAsinC (ii) sinAsinB+cosAcosB

In /_\A B C , right angled at B , if tanA=1/(sqrt(3)) , find the value of (i) sinAcosC+cosAsinC (ii) cosAcosC-sinAsinC

If A+B+C=180^(@), " then " (cosAcosC+cos(A+B)cos(B+C))/(cosAsinC-sin(A+B)cos(B+C)) simplifies to :
