The value of (sin30° cos60° - cos30° sin60°) is equal to:
Answer & explanation
Correct answer: option 2
We know ,
sin(A - B ) = sinA cosB - cosA sinB
Now , (sin30° cos60° - cos30° sin60°)
= sin ( 30° - 60° )
= - sin30°
The value of (sin30° cos60° - cos30° sin60°) is equal to:
Correct answer: option 2
We know ,
sin(A - B ) = sinA cosB - cosA sinB
Now , (sin30° cos60° - cos30° sin60°)
= sin ( 30° - 60° )
= - sin30°
