|
Answer» Step-by-step explanation:
Explanation: sin − 1 ( √ 3 2 ) = θ
means sin ( θ ) = √ 3 2
XXXX with the RESTRICTION that θ ∈ [ − π 2 , π 2 ]
The POSSIBLE TRIANGLES with this ratio of y to hypotenuse (i.e. sin ) are pictured below: enter image source here ...but note that only π 3 falls within the RESTRICTED range for sin − 1 |
