Given: The value of A is 30°.
To find: We have to find the value of sin2A.
Solution:
To determine the value of sin2A we have to follow the below steps as follows-
The given value of A is 30°.
Thus, the value of 2A is 30×2=60°.
Putting the value of 2A in the above expression of sin2A we get-
sin2A
sin60°
The value of sin60° is √3/2.
Thus, the value of sin2A is also √3/2.
Thus, the value of sin2A is √3/2.
