Question: In Exercises 1-4, determine whether the statement is true or false. Justify your answer 1. sin 5 / 6 = 1 / 2 arcsin

In Exercises 1-4, determine whether the statement is true or false. Justify your answer
1. sin 5π / 6 = 1 / 2 → arcsin 1 / 2 = 5π / 6
2. tan (- π / 4) = - 1 → arctan (-1) = - π / 4
3. arctan x = arcsin / arccos x
4. sin 1 x = 1 / sin x
