Evaluate sin 330°

We have to find the value of sin 330

Solution

sin 330 can be expressed as sin (360 – 30)

sin (360 -30) is in the identity form of sin (A + B)

sin(A-B)= sin AcosB-cosAsinB

sin (360 -30)= sin 360cos60 – cos 360.sin 30

As per the known values of sin and cos we will substitute in the above equation

sin (360 – 30) = 0.√3/2 – 1.1/2

= -1/2

sin 330= -1/2

Answer

sin 330= -1/2
