Answer 2

Answer:

The correct answer is (π−4).

Step-by-step explanation:

As we  know that,

n radian =(n×  

π

180°

​

)

Therefore,

1 radian ≈60°

⇒4 radian ≈240°

Therefore, 4 radian will lie in 3  

rd

 quadrant.

Therefore,

4 radian =π+x⇒x=(4−π)

Whereas, x is an acute angle

∴sin4=sin(π+x)=−sinx

∴sin  

−1

sin4=sin  

−1

(−sinx)=−x=−(4−π)=(π−4)

Therefore,

sin  

−1

(sin(4))=(π−4)

Hence the correct answer is (π−4).
