Find the exact value of the expression, if it is defined.
Sin-¹(sin(8pi/3))
Step 1
Read sin-1 x as the angle whose sine is x
Read sin x as, "the sine of the angle x."
Step 2
So, you are to find the angle in the interval [-pi/2,pi/2] whose sine is the sine of the angle 8pi/3, use verbal locución to give the answer. If your answer is undefined, enter UNDEFINED.
sin-¹(sin(8pi/3))=?
