Sin 60° cos 30° - cos 60° sin 30° =sin 30° – InterviewSolution

1.

Sin 60° cos 30° - cos 60° sin 30° =sin 30°

Answer»

$sin60 \times cos30 - cos60 \times sin30 \\$

It is in the FORM of

$\<klux>SIN</klux>(a) \cos(b) - \cos(a) \sin(b)$

which is EQUAL to Sin (a-b)

A= 60

B=30

$\sin(60 - 30) \\ \sin(30)$
