Find the exact value of arcsin(-sqrt(3/2)), using the theorem that y = arcsin x is equivalent to sin y = x with -1 ≤ x ≤ 1 and - π / 2 ≤ y ≤ π / 2

Let y = arcsin(- √3 / 2). According to theorem above, this is equivalent to sin y = - √3 / 2 , with - π / 2 ≤ y ≤ π / 2. From table of special angles sin (π /3) = √3 / 2. We also know that sin(-x) = - sin x. So sin(- π / 3) = - √3 / 2.Comparing the last expression with the equation sin y = - √3 / 2, we conclude that y = - π / 3.
