Answer 2

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.
