Sin30 cos30 -sin60 cos60 --------------------------------------1

sin30 =  \frac{1}{2}

cos30= \frac{ \sqrt{3} }{2}

sin60= \frac{ \sqrt{3} }{2}

cos60= \frac{1}{2}

Now A.T.Q

Putting all the values in the 1

 \frac{1}{2}  ×  \frac{ \sqrt{3} }{2}  \frac{ \sqrt{3} }{2}  ×  \frac{1}{2}

 \frac{ \sqrt{3} }{4}  \frac{ \sqrt{3} }{4}  = 0
