Question

Sin30 cos30 -sin60 cos60

Answer 1

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
