Question
The value of (sin 60 º cos 30 º - cos 60 º sin 30
º)  is equal to:Solution
(sin 60 º cos 30 º - cos 60 º sin 30 º) = √3/2 x √3/2 – 1/2 x 1/2 = 2/4 = 1/2 Alternate Solution sin A cos B - cos A sin B = sin (A - B) So, (sin 60 º cos 30 º - cos 60 º sin 30 º) = sin ( 60 º - 30 º) = sin 30 º = 1/2 Â
